In mechanical equipment, bearing is very common, and now I have to explain it with all of you is bearing the matters needing attention of needle roller bearings, hope I can for your reference. 1. After the bearings after installation, first for the axis of rotation or bearing box, without exception, with a power with no load, low speed, then according to the condition of operation gradually increase the speed and load, and detection noise, vibration and temperature rise, found abnormal, should stop and check; 2. When installation does not allow drilling, grooving on imported bearings, chamfering, surfacing. Otherwise, easy to cause the import bearing ring deformation, affecting the service life of bearings and precision, and cutting off the metal is easy to enter the bearing working surface, accelerate the raceway and rolling element wear and tear, cause premature bearing damage; 3. Pressure when installation should be added on the ring width of interference fit with installation, is installed on the shaft, the pressure should be added on the bearing inner ring end face; The load bearing hole, pressure should be added on the imported bearing outer ring end face. Don't allow through the rolling element and maintain delivery pressure; Through the related account, believe you specify the matters needing attention of needle roller bearings have specified extent understanding! Specified in the during the installation of the bearings, pay attention to the things mentioned above, and bearing specified in a good environment for use, if the oil temperature is too high, at least 3 months or more to replace a short time. What about needle roller bearings considerations of related issues here will come to an end, if you have the needle roller bearings price or other related problems are interested in, can call our telephone contact.
