Tennant Caster Wheel Assembly 3 x 1.38 – TN20833

This caster wheel assembly is sized 3 x 1.38 inches and built for Tennant sweeper and scrubber equipment, providing a pivoting support wheel that lets the machine maneuver and turn while carrying its own weight plus onboard tank fluid. As a complete assembly rather than a bare wheel, it includes the wheel and its mounting hardware together, ready to install in place of a worn unit.

Caster assemblies carry constant rolling and pivoting loads as the machine changes direction during cleaning passes, and that combination of rotational and swivel wear means the wheel tread and the pivot bearing both degrade over time. A worn caster typically shows up as wobble, uneven turning resistance, or a machine that pulls to one side, since the caster is no longer tracking true under load.

At 18 pounds, this is a substantial assembly consistent with a full-size caster built for a floor machine rather than a light-duty cart wheel. It is manufactured to fit Tennant equipment as a direct replacement, restoring stable, predictable steering without needing to rebuild the pivot mount separately.
