Solid Polyurethane

Expansion stem casters are designed to mount casters into open tubing fixtures. Turning of hex nut beneath the lower raceway on the caster expands the  rubber adapter inside of the round or square tubing for a tight fit. There are various stem sizes available which individually have a range of  tubing sizes the stem will fit into.

Solid polyurethane wheels are fantastic solutions for heavy wash-down and food grade environments. The solid polyurethane wheel provides a one piece molded solution which eliminates the issues of tread bond failures making them durable solutions for tough environments.
