Coated:
Our coated products are covered by a lifetime warranty.
The unique coating formula is a metallic layer that covers the bearing races and makes them 75% harder than steel.
Thanks to this, they are highly resistant to corrosion and the coating provides an even lower friction than our standard bearings.
Even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible if you choose the coated version.
