Mount these casters to the side of equipment or on gates and doors. They are spring-loaded for good shock absorption.

Tread-on-core wheels have a polypropylene core that is harder than the tread, balancing strength with cushioning.

Rubber wheels provide good traction on rough surfaces. Polyurethane wheels combine the abrasion resistance of plastic with the cushioning qualities of rubber. They can be used on smooth and rough floors and in areas with debris.

Sleeve wheel bearings prevent wear to the wheel bore but don't roll as easily as other bearings. Roller wheel bearings provide smoother rolling than sleeve bearings. Ball wheel bearings are the easiest to roll.

Casters have double-ball swivel bearings for the smoothest swiveling.
