Both the wheel bearings and the swivel bearings are protected to lengthen the life of these casters.

Hard rubber wheels are impact resistant and roll easily on smooth surfaces, but can be damaging to floors. Soft neoprene rubber wheels are shock absorbing and oil resistant. They work well on smooth and rough surfaces.

Rounded-tread wheels can turn more quickly than flat-tread wheels.

All wheel bearings are shielded to resist dust and debris. Sleeve wheel bearings prevent wear to the wheel bore but don't roll as easily as other bearings. Ball bearings are the easiest to roll.

Swivel casters have completely sealed double-ball bearings for the smoothest swiveling and the best protection against dust and debris.

To prevent rolling, choose casters with a wheel brake. Casters with wraparound brake have a rubber pad for a strong grip, making them easier to engage than casters with a face brake.
