Technology and design

The Dual Cup Technology system relies on two perfectly aligned aluminum cups, forming a rigid structure in the center of the housing. This eliminates play and unwanted noise.

The bearings used are hybrid ceramic models (ABEC5 / P5 – 2RS) ensuring optimal performance. The cups are made of 7075 aluminum, an aeronautical alloy treated T6 for increased robustness and longevity. The housing is fully sealed thanks to axial seals and complete surface protection.

Guarantee

The cups are guaranteed for life. The bearings have a 3-year warranty.
