Backing bearings are particularly thick outer ring of the rolling bearing, when used to form a group to be mounted on the shaft of a stationary support rollers. Pressure on the work roll through the intermediate roller and the support roller is passed to the system to the rack through the saddle. Generally used for multi-roll cold rolling mill equipment can also be used for other occasions, such as straightening machine.

which would help prevent damage to other components of the machine
must be taken to make ntn bearing installation and removal easy , saving time and labor expenses province . Operation Spherical roller bearings , hands sweat will become rusty reasons. To note with clean hands operation , the best possible gloves .
Remove the use of appropriate tools , which would help prevent damage to other components of the machine , remove the incorrect bearing technology might be damaged if the bearing reaches its ultimate use period of time , it should be replaced . While aligning lysn four row cylindrical roller bearing roller bearings can no longer be used, but the right to remove the original bearing , and timely replacement of new bearings , new bearings for extended life can play a good role in promoting and therefore replacement of old and new , is very important , which requires specialized personnel check operation
Using thermal sensors can move at any time to monitor the bearing temperature , and automatic alarm or stop to prevent burning shaft accident when the temperature lysn tapered roller bearing exceeds the designated value. Often expressed by high-temperature bearings in unusual circumstances . High temperature is also harmful to the bearing lubricant . Sometimes bearing overheating can be attributed to the bearing lubricant. If the self-aligning roller bearings at temperatures over 125 ℃ even move to reduce long bearing life . Causes high temperature bearings include: lack of lubrication or excessive lubrication, lubricant. Contains impurities , the load is too large, the bearing ring damage , lack of space , and high- friction seals and so on .
Therefore, continuous monitoring of temperature is necessary to move the bearing , ntn bearing bearing itself is a measure of whether or other important parts . If it is running under the same premise , any temperature change may indicate a fault has occurred. Schedule of the bearing temperature can be measured by means of a thermometer , digital thermometer for example , can be accurately measured spherical roller bearing temperature and given in accordance ℃ or Fahrenheit units.
