mill bearing temperature reason

What's normal: The role of temperature in bearing applications

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.get price

SKF provides tips on troubleshooting bearing temperatures

A simple rule for troubleshooting bearing temperatures: No more than 180 degrees Fahrenheit (82 degrees Celsius) on the housing. The bearing outer ring can be up to 20°F (11°C) hotter than the housing. The lubricant originally specified for the application was likely selected to run at lower temperatures. A temperature increase of 50°F (28get price

How to Prevent Bearings from Overheating

If the viscosity of the oil at the bearing operating temperature is two times or more than the minimum operating viscosity (from the bearing manufacturer), then you should reconsider the lubricant selection, especially for bearings operating near 3,600 rpm.

The reason of abnormal temperature of the vertical roller

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.get price

Lubrication Checkup: Gearbox Overheating Efficient Plant

Dec 19, 2013 Diagnosis: Judging by your description of the gearbox to the touch of a hand, I estimate its temperature to be around 150 F (or 65 C)—the approximate temperature when the hand has to be lifted within three seconds of touch.
