Plate Caster Model 9 Instructions:

You should never select on the basis of load capacity alone. Capacity ratings do not take into account the effort required to manually move a load. Capacity ratings are based on manual operation under ideal conditions. If these casters are going to be moved by mechanically powered equipment, consult us for a reduced capacity rating based on your application. If a human being has to move the weight, select the largest practical wheel diameter. If a caster failure occurs it is almost always because of misuse or abuse. It has been very rare that a product failed because of faulty material or poor workmanship. The following are examples of things that we do NOT want you to do:

1. Dragging the wheel sideways.
2. Shock or Impact caused by dropping the load instead of setting it down on the castered equipment.
3. Improper Installation such as:
A. Rigid casters not installed parallel to one another.
B. Swivel casters not installed parallel to the floor.
C. Using less than 4 bolts to attach the mounting plate.
D. Distortion of the swivel bearing when attaching the mounting plate due to welding improperly.
4. Exceeding the rated capacity of the wheel or caster.
5. Exceeding a rolling speed of 3 MPH.
6. The build up of heat caused by continuous operation causing tire separation.

Quick Change Plate – Zinc Plated

A zinc plated quick change plate gets bolted to your equipment and enables the casters to be easily and quickly installed or replaced (changed) without using tools.

Will ONLY fit the casters shown on this page WITHOUT the ( Total Lock ) Brake Option! Will NOT WORK with Pneumatic or Foam Filled Pneumatic casters. Will NOT WORK with 4 position swivel lock.

Caster Pad – Unplated – Caster Model 9

Unplated caster pad gets welded onto your equipment. It enables casters to be easily and quickly installed or replaced. For use with casters having a 4″ x 4 1/2″ Mounting Plate. Includes locking bolt installed as shown.

Will ONLY fit the casters shown on this page but WILL NOT FIT if you order the TL ( Total Lock ) Brake Option! Will NOT WORK with 4 position swivel lock.

Optional Features:

When purchased with Wheel Brakes, please note they are not designed to hold on inclines. Total Lock Brake Pedal Locks the Wheel and Swivel Simultaneously. Swivel Lock converts a swivel caster into a rigid caster for direct line travel. Weld on swivel lock option makes the caster non returnable.

We also now carry the Plastic Top Lock Brake, which works great as a field-installable, easy-to-use solution that can be retrofitted to Model 9 casters.

Plate Caster Model 9 Features:

img SWIVEL CONSTRUCTION: Cold forged top plate and yoke base from 1/4″ steel. Swivel has double ball bearing with hardened raceways.
img AXLE is 1/2” diameter hollow bolt with lock nut
img LEGS are 1/4″ thick, welded outside only
img GREASE FITTINGS For swivel and wheel bearings
img WHEEL BEARING options: B= Ball Bearings, BRNZ= Bronze, D= Delrin Bearings, PS= Precision Sealed Ball Bearings, P= Plain Bore, R= Roller Bearing.
img CENTER PIN 5/8″ diameter nut and bolt
img FINISH External metal parts are Zinc plated
img Other mounting plate sizes and wheel bearing types are available on request. Please call.

Typical Application Use for the Plate Caster Model 9 Series:

img Material Handling
img Moving Dollies
img Computer Equipment Stands
img Electronics & Diagnostic
img Office Equipment
img Laboratory Equipment
img Bakery Equipment Stocking Carts
img Food Service Carts
img Workstations

You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.
