About Casters and Wheels
More
Static-Control Plate Casters
The wheels dissipate static to protect sensitive electronic equipment from electrostatic discharge. Wheels are rubber for shock absorption.
Tread-on-core wheels have a core that is harder than the tread, balancing strength with cushioning.
Sleeve wheel bearings prevent wear to the wheel bore. Ball bearings are the easiest to roll. Shielded bearings protect the bearing from dust and debris. Sealed bearings are completely sealed for the best protection against dust and debris.
Swivel casters have double-ball bearings for the smoothest swiveling. Casters with wheel brake apply pressure to the wheel to stop movement with a press of the foot pedal. Casters with total lock brake the wheel and lock the swivel with one press of the foot pedal.
