4" x 2" Swivel Caster with Brake, Solid Polyurethane Wheel, 750 lbs Capacity

4"X 2" Blue Solid Polyurethane Wheel | Swivel Caster | 750 lbs Capacity Caster HQ's Blue Solid Polyurethane Elastomer wheel offers high weight capacities and great resistance to chemicals and wash-down applications. Our Blue Solid Poly Wheels are great for Steam Clean and full Wash-down applications while providing great floor protection and a quiet rolling operation. This wheel is great for clean rooms, labs, hospitals, and schools due to the non-marking high-quality polyurethane material. Optional precision ball bearings require less effort to start-up and maintain a rolling load; they also generate less friction heat and may prolong the life of the wheel. Works well in both indoor and outdoor environments; however solid polyurethane wheels may flat spot if they are left with a maximum load for long periods of time; if this is an issue look at using aluminum, iron, or plastic core wheels.
