SKF Two-wheeler

Floating Piston Seal

Floating piston seal

SKF offers an integrated sealing module for the pressure reservoir of two-wheeler shock absorbers, providing low friction for a better riding feeling and reduced nitrogen permeation for a longer suspension life. The floating piston from SKF replaces conventional solutions that typically consist of multiple parts with one single unit.

Product Application

Wheel

Seat post

Rear shock

Fork

eDrive unit

Features

Integrated unit with metal stamping and specifically developed rubber compound
External sealing lips with reduced friction provide virtually no stick and slip effects
Central membrane function to compensate for small amplitude vibrations without the need for the piston to move
Good gas and oil separation

Benefits

More stable operation due to reduced nitrogen permeation
Improved reliability as the special sealing lip design reduces oil leakage
Excellent dynamic sealing to avoid gas leakage
Better ride control and improved comfort through reduced friction and rubber membrane
Higher rider confidence as the rear wheel has more ground contact
Increased sensitivity for shock absorber tuning at the manufacturer, as there is less need to compensate for stick-slip and gas permeation over time
Simplified installation and logistics
