Can the correct selection of SKF bearings, the host can get a good performance and prolong life; pair enterprises can reduce maintenance time, reduce maintenance costs and increase machine uptime, have a very important role. Select the bearing but a science, because the market SKF bearing type a lot, so it should be considered in the selection of the following factors:
1. Payload size, direction and nature: ball bearings suitable for light load to bear, roller bearings suitable for heavy load and impact load. According to the bearing operating conditions (including the load direction and type of load, speed, lubrication, concentricity requirements, positioning or positioning, installation and maintenance of the environment, ambient temperature, etc.), select the bearing basic types, tolerance levels and clearance;
2．According to the bearing operating conditions and the forces and life requirements determined by calculation bearing type, or according to requirements, the selected bearing type, and then checking life; allowable speed: Due to different types of bearings are very different. Generally, the friction is small, less heat bearing suitable for high speeds. SKF Bearing design should strive to below the speed limit working conditions.
