, load, accuracy, size, lubrication, clearance, cage, and cooling conditions. However, the most important factor is the working temperature or lubricant allowed by the bearing material. The limit speeds of various types of bearings are listed in the bearing size and performance table of "Rolling Bearing Product Catalog". They are determined under the conditions of oil lubrication and grease lubrication, respectively, and their scope of application is:

1. Standard (G) level tolerance bearings

2. Radial bearings only bear radial load, thrust bearings only bear axial load

3. P is less than or equal to 0.1C (C is the basic dynamic load rating of the bearing)

4. Rigid shaft and bearing seat
