💡 Why use a polyurethane-coated miniature ball bearing?
Polyurethane bearings combine smooth rolling with excellent shock absorption and surface protection.

• Resists wear and tearing better than rubber

• Offers better load handling than plastic

• Absorbs vibrations in tight mechanical systems

• Ideal for high-speed, low-load rotating parts
