Description
Model 50 rigid casters and the matching swivel casters have the same wheels displayed on Plate Model 30. The weight capacity ratings in Model 50 are usually greater for the exact wheels shown in Model 30. The heavier and bigger mounting plate on Model 50, larger swivel bearing, and heavier legs are the reasons for the greater load capacity ratings shown on rigid model 50. Rigids are mostly used to control the direction when moving equipment in a direct line. The one exception are rigid plate casters which have v-groove wheels. V-groove wheels pivot on an inverted angle iron track which controls the line of travel. When swivel and rigid casters are on the same piece of machinery, swivel casters should be connected below the push handle, and rigid casters should be attached to the opposite end of where the push handle is located. Rigid casters can not move sideways. They require equipment to be maneuvered into place. Our recommendation is you use 4 swivel casters when maximum mobility is required in a confined work environment.
*This Plate Caster Model 50 contains the Polyurethane on Iron Wheel. The caster shown in photo with 10″ x 3″ wheel.

Polyurethane on Iron Caster Wheel from Caster City

Caster City’s PYH Industrial Caster Wheel is engineered for heavy-duty applications, featuring an extra thick ¾” polyurethane tire bonded to a robust cast iron core for superior load capacity and extended lifespan. Available in diameters from 6” to 12” and tread widths of 3” or 4”, the PYH wheel is designed to handle higher load ratings and more demanding conditions than standard polyurethane wheels of its size. Its Shore D 60 (+/- 5) durometer provides a harder tread, making it particularly suitable for supporting static loads while resisting flat spotting, provided the load does not exceed 70% of the wheel’s rated capacity in static applications.
The PYH wheel’s green polyurethane tire, combined with its heavy iron center, ensures durability and the ability to withstand arduous industrial environments. It offers a variety of bearing options, with tapered roller bearings as standard, and sealed precision ball bearings or roller bearings also available to optimize performance across different applications. The thicker tire enhances the wheel’s capacity to carry heavy loads and endure more abuse than comparable polyurethane wheels, making it an excellent choice for manufacturing, warehousing, or other high-demand settings where reliability is critical.
With a temperature range of -40°F to 180°F, the PYH Industrial Caster Wheel is built to perform in diverse conditions while maintaining its structural integrity. The harder durometer and extra thick tire design provide exceptional support for static loads, ensuring stability and longevity. For heavy-duty applications requiring a balance of high capacity, durability, and performance, the PYH wheel stands out as a top solution. Contact Caster City for custom configurations to meet your specific industrial needs with this versatile, high-performance caster wheel.
