Floating Piston - Ohlins Shock

The SKF Floating Piston for rear shocks is a cutting-edge replacement for the OEM gas-to-oil separator found in the reservoirs of these high-performance suspension systems. Unlike the conventional OEM separators, typically constructed with a rigid plastic or metal body and a thick O-ring seal, the SKF Floating Piston introduces a revolutionary design to enhance shock performance.Traditional separators cause considerable friction during vertical movement, impeding the shock's responsiveness to small, high-frequency bump absorption. Existing solutions involve multiple parts, such as a piston with a rubber O-ring and friction strip or a rubber bladder. The SKF Floating Piston simplifies this complexity by integrating these functions into one unit, preserving the advantages while mitigating drawbacks.Crafted using SKF's special low-friction compound, the Floating Piston replaces the OEM separator without altering the reservoir design. It features two sealing lips against the reservoir walls, ensuring a perfect seal and effective separation between oil and gas. The central portion of the piston membrane is designed with flexibility, enhancing shock reactivity to small bump absorption.The SKF Floating Piston-equipped reservoir enhances shock reactivity, particularly in absorbing high-frequency small bumps and following oil transfers between the body and reservoir. The flexible center membrane anticipates piston movement, improving responsiveness.SKF's integrated sealing module for two-wheeler shock absorber pressure reservoirs offers low friction for a smoother riding experience and reduces nitrogen permeation for an extended suspension life.The piston is an integrated unit with precision metal stamping and utilizes a specially developed HNBR or NBR rubber compound. This not only ensures durability but also contributes to optimal shock performance. The external sealing lips are engineered with reduced friction, effectively minimizing stick and slip effects. This feature enhances the overall smoothness of the shock's operation. The design minimizes the need to compensate for stick-slip and gas permeation during shock absorber tuning, increases sensitivity and allows for precise adjustments. The special sealing lip design is implemented to minimize oil leakage, enhancing the overall reliability of the shock absorber.The piston includes a central membrane designed to compensate for small amplitude vibrations without necessitating piston movement. This innovative feature contributes to a more responsive and comfortable ride. The reduced membrane surface ensures more stable operation by allowing less nitrogen permeation compared to bladder solutions. This contributes to a consistent and reliable performance, improved ride control and comfort. The shock operates with heightened smoothness, translating to a more comfortable riding experience.The special compound characteristics and lip design play a pivotal role in achieving effective gas and oil separation. This is crucial for maintaining the integrity and performance of the shock absorber. With improved rear wheel ground contact, riders can have higher confidence in the stability and responsiveness of their bikes.The integration of multiple functions into one part simplifies the installation process and streamlines logistics, offering practical benefits to both manufacturers and end-users.The SKF Floating Piston stands as a testament to innovation and engineering excellence, providing a comprehensive solution that addresses multiple aspects of shock absorber performance and reliability.
