Bearing Materials for Earthmoving Equipment

There are many types of bearings available that can be used for Off-Highway types of equipment. In fact, so many, that they can be classed in such a manner that the static capacity, dynamic capacity, velocity limits and temperature capability can be graduated to assist the designer in choosing a suitable material. A concise outline of both metal-backed, lubricated and self-lubricated bearings will be outlined along various types of self-lubricated, high-strength composites. Guidelines to choose a material based on application data will also be reviewed.
