Normal motor bearing operating temperatures range from 140° to 160°F. As in all bearing applications, this measurement should be taken at the bearing outer ring. If the outer ring is inaccessible, take the measurement at the housing and add 15° to 20°F to estimate the correct bearing temperature.

Drastic changes in temperature can also affect spindles and bearings. A dry area that does not fluctuate outside of 65°-120° Fahrenheit is ideal for storage. In addition to stable temperatures, stable levels of vibration are also important when it comes to storing spindles.

These bearings can with-stand operational temperatures which are in the range of 80 deg C to 120 deg C. Beyond these temperatures fibre bearings generally get charred. Water is used as a general source for lubrication on fibre bearing. These bearings are cheaper than metallic slider bearings and have higher load carrying capacities.

One is that if grease lubrication were employed for the bearings of high-speed machines, the operating temperatures would be so high that regreasing would be required much too often. Then, excessive grease could contaminate the machine. Another reason for using oil on felt-roll bearings is that there are surely other oil-lubricated bearings nearby.

Vertical mill roller bearings have a relatively high operating temperature, and the internal temperature of the bearing is close to 200 ° C. If the type of lubricating oil is not correct, the oil used for lubrication will deteriorate or be evaporated due to high temperature and high pressure, thus losing the roller bearing.
