Polyurethane-on-polyolefin (PU on PO) wheel casters designed for light-duty carts and mobile equipment where floor protection, quiet rolling, and non-marking performance are required in institutional and commercial environments.
PU on PO wheels combine a resilient polyurethane tread for floor protection with a rigid polyolefin core for dimensional stability under load. This construction provides quieter rolling and reduced vibration compared with harder wheel materials.
Precision sealed ball bearings are commonly specified to support smooth rolling and reduced maintenance in institutional service environments.
