Technology and design

Dual Cup technology relies on two precision-machined aluminum cups, ensuring perfect bearing alignment. This assembly creates a rigid central connection that eliminates unwanted noise and movement.

Steel bearings (ABEC5 / P5 – 2RS) ensure excellent durability and consistent performance. The cups are made of aircraft-grade 7075 aluminum, with a T6 treatment for increased durability over time.

Fully sealed, the housing is protected by axial seals on the bearings and complete sealing on all surfaces. The number of pins has been reduced to reduce weight without compromising its robustness.

Guarantee

• Lifetime warranty on cups
• 3-year warranty on bearings
