Roller Balls

Tabletops or work surfaces with roller balls can help reduce friction force when workers are moving, loading, or positioning large sheets of metal, wood, or pipe into a machine. Pushing or sliding objects eliminates lifting and carrying that can be more strenuous for the arms and back.

Existing work surfaces and tables can be outfitted with roller tops, and some rollers are capable of rotating 360 degrees, which allows for objects to be rotated and turned easily. Powered rollers minimize pushing and pulling forces.

When installing roller ball systems, keep in mind that objects are easier to push or slide when they are at waist height. Roller ball surfaces require regular maintenance to minimize pushing and pulling forces. Also, make sure that employees are aware of pinch hazards when working around roller balls.
