Product Overview

4" X 2" Crowned Gray Thermo Rubber (Non-Marking) Wheel - 350 Lbs Capacity

CasterHQ's 4" x 2" Crowned Thermo Plastic Rubber (TPR) wheels are built for durability and performance. Featuring a non-marking gray TPR tread bonded to a Polyolefin core, these wheels are ideal for industries like food service, hospitals, and labs. With a 75 Shore A durometer, they roll smoothly over debris and obstacles. The crowned tread design offers reduced push/pull resistance for effortless movement.

These soft, non-marring wheels absorb shocks and vibrations, protecting floors and equipment. They offer a quiet ride but should not be used for long-term stationary loads to avoid flat spots. Avoid harsh chemicals or excessive heat to maintain tread quality. Contact us for any application questions.

***Crowned tread wheels are easier to roll with less resistance compared to flat tread, though they absorb less shock and vibration.***
