💡 Why choose a polyurethane-coated bearing for your setup?
PU-coated bearings add toughness where it counts - especially in high-impact spots.

• Absorbs shock better than hard plastic

• More tear and abrasion resistance than rubber

• Reduces noise and vibration in motion

• Great for robotics, guides, conveyors, and wheels

If you need a tough little bearing that keeps rolling where others wear out, this PU-coated one’s your go-to - add it to your cart and let it do the heavy lifting.
