4 in Polyurethane Threaded Stem Caster 286 lbs Load for Industrial, Pkg Qty 10

Overview

This heavy-duty threaded stem caster is engineered for demanding industrial material handling applications where floor protection and high load capacity are critical. Featuring a 4-inch polyurethane wheel, the unit supports up to 286 lbs while ensuring smooth, quiet operation on sensitive surfaces such as epoxy, tile, or sealed concrete. The robust construction resists abrasion, chemicals, and debris, making it ideal for facilities that require reliable mobility without compromising floor integrity. With an overall installation height of 5.7 inches and a precision-threaded mounting system, this caster integrates seamlessly into existing equipment frameworks for immediate deployment in manufacturing, warehousing, and logistics environments.

Applications

Industrial machinery relocation and positioning Warehouse order picking carts and shelving units Food processing equipment requiring non-marking wheels Hospitality service carts needing quiet operation Automotive assembly line tooling transport Laboratory equipment mobility in clean environments Retail stockroom inventory management systems The polyurethane tread formulation provides an optimal balance between hardness and elasticity, delivering superior roll resistance compared to rubber while maintaining greater shock absorption than nylon or phenolic alternatives. This makes the caster particularly effective for transporting delicate loads across uneven transitions or expansion joints commonly found in large facilities. The threaded stem configuration eliminates the need for additional locking hardware in most applications, as the tension fit within the receiver tube prevents accidental dislodgement during dynamic movement. Each unit undergoes rigorous quality validation to ensure consistent performance under continuous cyclic loading, supporting uptime-critical operations where equipment failure results in costly production delays. The standardized metric thread dimensions are widely compatible with international equipment frames, while the imperial load and size specifications align with North American procurement standards for ease of integration into existing fleets.
