Dual Wheel casters provide a high load capacity with a minimum overall height. The larger footprint ( two wheels instead of one ) enhances stability and spreads the load over a larger floor area. The differential action inherent in all swivel dual wheel casters minimizes the effort required to change directions.
Our Dual Wheel casters are designed to offer a perfect blend of strength, stability, and ease of use. These casters are the perfect solution when you need to move heavy loads around your facility or worksite. With a high load capacity and a minimum overall height, these casters are suitable for a wide range of applications, including material handling, machinery, and equipment. Another benefit of dual wheel casters is their ability to handle rough or uneven terrain. The larger footprint and differential action make them ideal for use in outdoor or industrial environments where the ground may not be level or smooth. This can improve safety and efficiency by allowing workers to move heavy loads with greater ease and stability.
When it comes to casters that can withstand heavy loads, Caster City’s Model 2-150 is the go-to for many industries.

Threaded stem casters are the most common type of stem caster. They have a threaded stem on top that screws into a tapped threaded hole, passes through a hole in which it is held in place with your lock washer and nut, or a welded nut inside of tubing. Caster City’s stem casters allow your equipment to roll, which reduces the effort it takes to move or reposition the equipment. Threaded stem casters are typically used when there is not enough room on the equipment’s mounting surface to attach a plate caster’s mounting plate.
Expanding rubber stem casters are designed to mount the caster into round or square tubing. Turning the hex nut beneath the lower raceway on the swivel caster expands the rubber stem adapter inside of the round or square tubing for a tight fit, as shown here. Caster City offers various expanding rubber stem sizes. Caster City manufactures expanding rubber stem kits to fit an Inner Diameter range of 3/4″ to 1-13/16″ Inner Diameter metal tubing. See the chart below.
Grip ring stem casters come in two sizes and are designed to fit into tubing or a socket that is securely attached to the equipment. The grip ring, also called a compression ring, is a ring on the stem that compresses as it is pressed up into the tubing or socket. It is squeezed and then expands against the tubing walls which creates the force that keeps the casters from falling out should the equipment come off of the ground or floor. Load capacities range from 80lbs to 300lbs.
Caster City manufactures stem casters that have one or more cross holes to bolt the stem of the caster into equipment. The stems are solid metal with a round or square shape. They can be attached to equipment built from structural framing to allow the equipment to roll or move. The shape and size of the stem determines the type of frame the caster will fit into. Pins or bolts are installed into cross-drilled mounting holes in the framing and the caster’s stem to secure the caster in place on the equipment. Load capacities up to 300lbs per each stem caster.
Hollow Kingpin casters have a 1/2″ diameter hole in the center of a swivel caster where the stem would normally be. This design enables you to supply your own bolt for a stem so you can use any length needed for your application. Hollow Kingpin casters are typically used when there is not enough room on the equipment’s mounting surface to attach a plate. This caster has a 1/2″ diameter hole for your BOLT.
Caster City manufactures all of our zinc plated stem casters in stainless steel. Every stem size and type that we offer in zinc is also offered in stainless steel. Caster city manufactures all of our institutional casters with a stamped 304 stainless steel construction and are excellent for corrosive applications. Our stainless Steel stem casters can support up to 300 lbs each, depending on the stem type and wheel selection.

T-Nuts can be used to secure our threaded stem casters to wooden items. Here we show the typical use of the T-Nut for both a Horizontal and a Vertical Application.
In the Horizontal Application, you would drill a hole equal to the diameter of the barrel of the T-Nut and completely thru your wood. Hammer the T-Nut into the hole and thread your caster in from the bottom. This is the strongest mounting.
The Vertical Application is for attaching casters to the bottom of legs and into the end grain of the wood. This is not an exceptionally strong way to mount! Drill your hole equal to the diameter of the barrel of the T-Nut and to the depth of the length of the stem of the caster plus about 1/4″. Apply 2 part epoxy to the T-Nut for additional strength. Hammer the T-Nut into the hole and thread your caster in from the bottom. You must use epoxy as we have had problems with some woods where the nuts ( and the casters ) fall off.
These industrial pneumatic casters feature air filled pneumatic wheels. These industrial casters are designed for low speed manually moved applications only. Air filled pneumatic wheels provide a cushioned ride, shock absorption and quiet operation. Pneumatic casters are ideally suited for moving fragile or delicate cargo where caster overall height is not critical. Casters with pneumatic wheels are usually the best choice for use outdoors over rough surfaces ( i.e. gravel ) or on grass. The wide footprint on 8″ or larger pneumatic wheels provides stability on gravel and does not sink into lawns.
Pneumatic casters and pneumatic wheels are also popular for indoor use in places such as hospitals, scientific and electronic laboratories, hotels, department stores and TV or movie studios.
Pneumatic wheels with black tires do not mark the floor as long as the wheel is allowed to roll. Changing directions without allowing a swivel caster to turn gradually around, or dragging a black rubber wheel sideways, can mark some floors.
These industrial casters are designed for low speed manually moved applications only. Foam Filled Pneumatic Wheels have NO air in the tires, thus eliminating the possibility of the wheels ever going flat.
Foam Filled wheels do NOT have any resilience. They provide the same traction and wide footprint of air filled wheels which enables them to roll on grass, dirt and over small pebbles.
Foam Filled Pneumatic Wheels have a higher initial cost than Air Filled Pneumatic Wheels. However, over time, they may prove to cost less because they last longer and avoid down time due to loss of air. Since people tend to load equipment only to the weight they can move easily,
Foam Filled Pneumatic Wheels can lead to higher productivity because they require less effort to move than pneumatics that are under inflated.
Our Elite Series Chrome Chair Casters offers soft ray rubber wheels which can not mark or damage hardwood floors. The soft rubber wheel is available in both 2″ and 3″ diameters. Although we do not recommend any caster for a SOFT WOOD floor such as Pine, the Elite series with it’s extra soft rubber wheels has been used successfully on SOFT WOOD floors.
These chair casters are for use on Hardwood or ANY hard floor surface. Many home owners and businesses are tearing out carpeting and installing wood floors. To protect these floors you need to use a soft wheel. Although most recommendations are for a soft rubber wheel on hardwood, a soft polyurethane caster wheel can also be used on hardwood floors.
Most of the office chairs that are manufactured today come with twin wheel nylon casters. This type of caster, specifically the nylon wheel, can be used on carpeting but it will mark and scratch all wood floors. It happens because the nylon wheels don’t roll, they slide. When they slide, they mark or scratch the floor. Our selection of hard wood chair casters is the ideal solution for this problem. The soft rubber wheels on our chair casters for hardwood floors will not mark or scratch the floors.
The Chrome Caster, our Elite series, offers both soft rubber wheels for hardwood floors and a stylish polyurethane wheel which can be used on either hardwood floors or carpeting.

The High Temperature Phenolic Wheels ( prefix “TP” ) , the High Temperature Glass-Filled Nylon wheels ( prefix “NP” ), and the High Temperture “OV” Epoxy Resin Wheels have a hard surface and should be used on smooth floor surfaces. If the floors are rough or if there are obstructions which will impact these wheels it will reduce the service life of the wheels. In any high temperature application it is always best to shield High Temperature Wheels from a direct heat intake source. Consult us for a load capacity rating in your application. We will need the following information: Maximum Temperature and for how long? Maximum load on each caster? Is your application wet or dry?
Phenolic caster wheels are made from macerated canvas mixed with phenolic resin, and molded under high pressure and temperature. Its hardness is comparable to polished maple flooring. Phenolic caster wheels are recommended for smooth concrete and can be used for storage (standing) loads without permanent set. These caster wheels are highly resistant to oil, grease, gasoline and mild acids. It is not recommended for wet applications where the wheel will be in standing water. They are affected in various degrees by strong acids and some alkaline solutions. Temperature range is -40° to +250° F, with intermittent use up to 300° F. Phenolic caster wheels will carry loads as great as the same size iron wheel. The wheel material may chip or cut from contact with steel plate or from rolling over steel parts on the floor. The wheel tread may show wear from repeated travel over rough surfaces. Floor wear is slight except where floors are already starting to deteriorate. These wheels can be made with a laminated unmacerated tread to provide 25% more capacity and greater chip resistance.
These wheels provide high load capacity without causing floor wear associated with metal wheels. Unlike polyurethane wheels, there is no risk of flat spots or delamination if these wheels are left parked for a prolonged period. Instead of injection molding, these wheels are compression molded and then machined. Their straight sided shape maximizes load capacity.
V-groove caster wheels are designed to guide equipment by rolling on inverted angle iron track. Elevated track minimizes problems caused by floor debris. The relief groove at the base of the “V” equalizes the load on each face of the angle. Forged Steel V-groove caster wheels minimize wear of the V-groove sides and are best for frequent operation. When not operating on track, the considerable wheel tread on each side of the V-groove allows for use on smooth floors. It is important that if more than one track is used they are parallel, straight and level. Otherwise V-groove wheels may bind or run up over the track. Tolerance should be within plus or minus 1/64″ every 20 feet. Joints between pieces of track should be smooth and well reinforced. V-groove caster wheels are standard with straight roller bearings, which allow only 1/16″ total end play (side to side movement). It is desirable when loads are great to use tapered bearings, which have thrust as well as radial capacity. The proper adjustment of tapered bearings prohibits end play. Compression must be applied to properly seat tapered bearings. This is achieved by tightening down against a bearing spacer on each side of the wheel to a maximum looseness of .010. Since tapered bearings prohibit end play, their use requires parallel track. Unless the layout is nearly perfect, it is best to use a single angle iron track for V-groove caster wheels parallel to an elevated flat bed for wheels without a V-groove.
White Nylon Caster Wheels are made with a solid nylon material. Black Nylon Caster Wheels are reinforced with glass fiber to increase capacity and reduce friction when rolling.
These wheels weigh very little yet they have a load capacity comparable to most metal wheels. They will not develop a flat spot. Nylon wheels are a better choice in wet and corrosive applications which require both chemical resistance and a higher load capacity.
Not recommended if the acid content exceeds 10% of your solution.
These caster wheels have non-marking injection molded thermoplastic rubber tires mechanically bonded to a polyolefin ( industrial plastic ) center. They are popular on equipment in Pharmaceutical Laboratories, Hospitals, Food Service and other Institutional applications. These caster wheels provide a softer ride than polyurethane and yet withstand exposure to many chemicals and solvents. They can be used in industrial applications which do not involve shock, overloading, abuse, obstructions, poor floors or storage (standing) loads. Wheels with RH prefix have a slightly higher capacity than our other gray soft rubber wheels.
Polyurethane caster wheels are non marking and non conductive. The absence of a metal center eliminates bond failure as a cause for wheel replacement. These caster wheels are especially suited for use with stainless steel casters in wet and corrosive applications.
They are designed for use in Pharmaceutical Laboratories, Hospitals, and Food Processing Plants – wherever a clean sanitary design is desired. These wheels are not recommended for applications involving shock, overloading, abuse, obstructions, poor floors, or for storage (standing) loads. Hardness is 60 – 65 Durometer Shore D. Temperature range is -20° to 180° F. Standard wheel color is Blue.
These wheels are designed for use in a wet environment and they eliminate the possibility of tire separation.

Polyolefin Caster Wheels are injection molded from a blend of thermoplastic polymers forming a one piece solid sanitary design. These Polyolefin wheels, as with Nylon wheels, are especially suited for wet and corrosive applications. They are very resistant to most commonly encountered liquids. Polyolefin wheels have a lower capacity and a more limited temperature range than Nylon wheels with the exception of our Extra Heavy Duty Polyolefin wheels ( prefix RK ). In a cold dry environment, such as a refrigerated store room, Polyolefin wheels may become brittle. They should not be used in a freezer or a heat application above 180°F intermittent usage, such as a rack washer.
Our Extra Heavy Duty Polyolefin Caster Wheels ( prefix RK in the part number ) are reinforced with glass fiber to increase capacity and temperature range. These Extra Heavy Polyolefin wheels are comparable to Nylon wheels in load capacity. They are also especially suited for wet and corrosive applications. Extra Heavy Duty Polyolefin wheels are standard with Non-Stainless Precision Sealed Ball Bearings ( PS ) and Stainless Precision Sealed Ball Bearings ( SPS ).
Not recommended if the acid content exceeds 10% of your solution.
