用于WP和Ohlins激波的SKF浮动活塞是其OEM气油分离器的替代品，该分离器存在于这些激波的储层中。OEM分离器通常由刚性塑料或金属体制成，并由厚O形密封圈围绕在储液罐体内。这种类型的设计会对分离器的垂直运动产生明显的摩擦，使冲击难以对小的高频冲击吸收作出反应。SKF浮动活塞设计用于取代OEM分离器，而无需更换OEM储液罐设计。SKF浮动活塞使用SKF专用低摩擦化合物制成。它具有两个密封唇，紧靠储层壁，实现油气之间的完美密封和分离。此外，活塞膜的中心部分设计有一定程度的灵活性。配备SKF浮动活塞的储油器允许在吸收高频小颠簸和跟随油从储油器/向储油器转移到车身时提高冲击的反应性。柔性中心膜片首先开始变形，预计活塞会完全移动，从而增强对小碰撞吸收的冲击反应。
SKF floating piston for WP and Ohlins shocks is a replacement to their OEM gas to oil separator which is present in the reservoir of those shocks. OEM separator is normally built with a rigid plastic or metal body surrounded with a thick O-ring sealing into the reservoir body. This type of design causes significant friction against vertical movement of the separator, making it difficult for the shock to react to small high frequency bump absorption. 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.
