INA bushings with ELGOGLIDE® sliding fabric are used for supporting the wheels that can be axially adjusted along the wheelset axle. These low-friction, cylindrical radial dry plain bearings comprise a steel supporting body on which the ELGOGLIDE® sliding fabric is securely fixed using a moisture-resistant adhesive bond.
These INA bearings require zero maintenance and do not require lubrication. They have already proven themselves in regular service and have an expected operating life of over 500,000 km. Maintenance-free cylindrical bushings have a very high radial load carrying capacity as well as a good damping characteristics.
