Gas springs are used to assist opening, closing, lifting, lowering and damping, movements, for example to support the tailgate or bonnet of a car. There are also many applications in general industry, for example in office chairs or kitchen cupboards.
Gas spring seals
Gas springs are devices used to lift and support in automotive and general industrial applications. The function of the seal is critical for the function of the gas spring.
SKF polymer ball bearings are typically used in applications where resistance to moisture or chemicals is essential and steel bearings cannot be used or only with certain restrictions. In those applications, polymer ball bearings are an excellent solution from both a technical and economic perspective as they are characterized by the following properties:
NoWear is a wear-resistant carbon coating that can be applied to the rolling elements and inner ring raceway(s) of a bearing (designation suffix L7DA) or only the rolling elements (designation suffix L5DA).
Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride (Si3N4). Because the silicon nitride ceramic material is such an excellent electrical insulator, hybrid bearings can be used to effectively insulate the housing from the shaft in both AC and DC motors as well as in generators.
SKF sensor bearing units are used to accurately monitor the status of rotating or linear components. These units are:
