Polyurethane bearings typically refer to bearing components that incorporate polyurethane as a coating or outer layer, combined with a metal or plastic bearing core. This design provides the strength of traditional bearings along with the wear resistance and flexibility of polyurethane.

Unlike standard bearings, PU-coated bearings offer reduced noise, improved surface protection, and enhanced durability, making them ideal for applications involving continuous movement and surface contact.

Key Features

Smooth and Quiet Operation: Reduces noise compared to standard metal contact.

Excellent Wear Resistance: Polyurethane surface withstands long-term friction.

Surface Protection: Prevents damage to conveyed materials or tracks.

High Load Capacity: Metal core ensures structural strength.

Low Rolling Resistance: Enables efficient and stable movement.

Long Service Life: Combines durability and resilience.
