Description
The Swivel Lock and the Wheel Brake Options may add 1 week to the lead time. They are not returnable if ordered with either option.
The Plate Caster Model 150 with PYH Premium Polyurethane on Iron Wheels is engineered for heavy-duty industrial tasks, combining a robust 8-1/2″ x 8-1/2″ top plate and ½-inch thick steel legs with a high-capacity PYH wheel. The PYH wheel, featuring a ¾-inch thick polyurethane tire (Shore D 60 ± 5) bonded to a cast iron core, supports up to 6,500 lbs per wheel (12″ x 4″), ideal for tow-line applications, static loads, and demanding environments like automotive plants, boat/yacht building, and observatories. Its non-marking tire protects floors, resists flat spotting, and withstands chemicals, operating reliably from -40°F to 180°F. With bearing options like heavy-duty needle roller, precision sealed ball, or tapered roller, the PYH wheel ensures smooth rolling and low drawbar pull, making it a top choice for precision and durability.
Built for longevity, the Model 150’s precision-machined swivel bearing reduces vibration, while the PYH wheel’s thick tire and 60 Shore D durometer handle continuous use without wear. Available in 4-inch wide wheels with 6-inch, 8-inch, 10-inch, or 12-inch diameters, it’s perfect for moving yacht hulls, telescope roofs, or heavy machinery carts without damaging surfaces. For powered tow-lines or unique setups, contact Caster City at 800-501-3808 or sales@castercity.com to customize your solution. Purchase directly online and experience unmatched performance in high-capacity, floor-friendly applications.
In a manufacturing facility where carts haul massive loads across the floor, Caster City’s Heavy Duty Industrial Caster – Model 150 gets the job done with a 20,000 lbs capacity, an 8-1/2” x 8-1/2” top plate, and 7” x 7” bolt hole spacing, featuring a precision machined 7” swivel bearing and 1-1/4” tapered roller bearings for smooth operation at speeds up to 3 mph. Equipped with grease fittings, a zinc-plated finish, and an optional bolt-on swivel lock, this caster is built for heavy-duty industrial use but isn’t made for abuse beyond its capacity—avoid rough conditions or overloading, and contact Caster City at 800-501-3808 for mechanically powered equipment recommendations.

FAQ
Plate Caster Model 150 with PYH Premium Polyurethane on Iron Wheel FAQ
What is the weight capacity of the Plate Caster Model 150 with PYH polyurethane wheels?
The PYH polyurethane wheel supports up to 6,500 lbs per wheel for the 12″ x 4″ size, offering higher capacity than standard polyurethane wheels, while the Model 150 caster bracket handles up to 20,000 lbs under ideal conditions (smooth floors, manual movement at 3 mph). The wheel’s capacity limits each caster to 6,500 lbs for larger sizes. For specific load ratings or powered applications, contact Caster City at 800-501-3808.
What wheel sizes are available for the Plate Caster Model 150 with PYH polyurethane wheels?
For the Model 150, PYH polyurethane wheels are 4 inches wide and available in 6-inch, 8-inch, 10-inch, or 12-inch diameters. Choose the diameter based on your load and floor conditions—larger wheels, like the 12-inch, support higher capacities and improve mobility on uneven surfaces.
What materials are used in the Plate Caster Model 150 with PYH polyurethane wheels?
The caster is constructed from ASTM1045 drop-forged steel with a 5/8” thick swivel head, 1/2” thick double-welded legs, and a 7” raceway with 3/4” hardened steel ball bearings, all zinc-plated for corrosion resistance. The PYH wheel features a ¾-inch thick polyurethane tire (Shore D 60 ± 5) bonded to a heavy cast iron core for durability and extended life.
Why choose PYH polyurethane wheels for the Plate Caster Model 150?
PYH wheels are built for high-capacity, long-lasting performance, with an extra thick ¾-inch polyurethane tire that supports up to 6,500 lbs (12″ x 4″) and resists wear and flat spotting, ideal for tow-line and static load applications. Non-marking and floor-protecting, they offer smooth rolling with heavy-duty needle roller, precision sealed ball, or tapered roller bearings for low drawbar pull, perfect for demanding settings like automotive plants.
What bearings are used in the PYH polyurethane wheels for the Plate Caster Model 150?
PYH wheels come standard with tapered roller bearings for high load support, with options for heavy-duty needle roller bearings or precision sealed ball bearings to optimize performance in tow-line, static load, or high-mobility applications. For help choosing bearings, call Caster City at 800-501-3808.
Can the Plate Caster Model 150 with PYH polyurethane wheels operate in demanding environments?
Yes, it operates from -40°F to 180°F and resists oil, grease, and most chemicals, making it suitable for automotive tow-lines, boat building, or observatories. The thick tire and cast iron core ensure durability in continuous-use or static load scenarios. For extreme conditions, email Caster City at sales@castercity.com.
How do PYH polyurethane wheels in the Plate Caster Model 150 protect factory floors?
The 60 Shore D polyurethane tire is non-marking, absorbs impacts, and minimizes floor wear compared to steel wheels, ideal for automotive plants, shipyards, or observatories. For sensitive floors, V-groove wheels on angle iron tracks add protection—contact Caster City at sales@castercity.com for recommendations.
Which industries use the Plate Caster Model 150 with PYH polyurethane wheels?
It’s a top choice for automotive, aerospace, boat/yacht building, observatories, heavy manufacturing, warehouses, and defense. It supports tow-line applications, yacht hull transport, telescope roof movement, aircraft component handling, and heavy carts, prioritizing high capacity and floor protection.
What are the primary applications for the PYH polyurethane wheels in the Plate Caster Model 150?
They excel in automotive tow-lines (vehicle parts), boat/yacht building (hull and mold transport), observatories (telescope roof movement), aerospace (aircraft components), heavy manufacturing (machinery carts), warehouses (goods transport), and defense (helipads or fortifications). They resist flat spotting for static loads and reduce noise in precision environments.
How do I maintain the Plate Caster Model 150 with PYH polyurethane wheels?
Lubricate the grease fittings on the caster’s raceway and axle regularly to ensure smooth, quiet operation, especially for tow-line or static load applications in automotive or observatory settings. The PYH wheel’s bearings are maintenance-free, enhancing uptime.
Can the Plate Caster Model 150 with PYH polyurethane wheels be used with mechanically powered equipment?
It’s optimized for manual or tow-line applications, but powered use is possible with customization. Contact Caster City at 800-501-3808 to ensure a safe setup for powered equipment, such as automotive tow-line systems, leveraging the PYH wheel’s low drawbar pull.
