The ball bearing reduces friction between rotating parts, enabling smooth 360-degree rotation and easy movement of furniture while supporting both radial and axial loads.
Consider load capacity, speed requirements, environmental conditions (moisture/dust), and compatibility with caster dimensions. Chrome steel bearings are standard; stainless steel offers corrosion resistance for damp environments.
Most are sealed and lubricated for life. Periodic inspection for smooth rotation and cleaning of debris is recommended. Avoid excessive side loads that can cause premature failure.
