SKF Floating piston is designed to replace OEM separator without having to replace the OEM reservoir design. The SKF floating piston is made using the SKF special low friction compound. It features two sealing lips against the reservoir walls for perfect seal and separation between oil and gas. Moreover the central portion of the piston membrane is designed with a level of flexibility.

The SKF Floating piston equipped reservoir allows for increased reactivity of the shock in absorbing high frequency small bumps and in following the oil transfers from/to the body from/to the reservoir. The flexible center membrane starts deforming first, anticipating the complete piston movement, thus enhancing the shock reactivity to small bump absorption.
