Debris-Guard Casters with Rubber Wheels

Metal wheel guards keep dust and debris from restricting motion.

Mounting Plate Style 1


Rigid	Swivel

Neoprene—Neoprene wheels are oil resistant.

Soft—Soft wheels are shock absorbing and provide good traction on rough surfaces.

Swivel—Swivel casters have dual-raceway bearings for the smoothest swiveling.

Roller Bearings—Roller wheel bearings provide smooth rolling.

Sealed Bearing—Sealed bearings are completely sealed for the best protection against dust and debris.

Mounting Plate Style 2


Rigid	Swivel

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

Soft—Soft wheels are shock absorbing and provide good traction on rough surfaces.

Hard—Hard wheels are impact resistant and roll easily on smooth surfaces, but can be damaging to floors.

Swivel—Swivel casters have dual-raceway bearings for the smoothest swiveling.

Without Bearing—Casters without wheel bearings have a wheel that rides directly on the axle, making them an economical choice for equipment not frequently moved.

Wheel Brakes for Swivel Casters—Add wheel brakes to prevent the caster from rolling.
