💡 Why use polyurethane coated ball bearings in rolling and guiding applications?
Polyurethane covered bearings are designed to combine smooth rotation with surface protection and impact control.

• Polyurethane layer improves abrasion resistance compared to bare steel

• Softer contact surface helps reduce noise and vibration during rolling

• Strong steel core maintains load capacity while the coating protects mating surfaces

This bearing helps keep rolling motion smooth and controlled while improving durability in systems that see repeated contact and surface wear.
