In addition to the inspection before the bearing equipment, the radial clearance of the bearing shall also be tested. The radial clearance mainly includes the original clearance of the bearing under natural conditions, the cooperative clearance caused by the change of the original clearance after the bearing equipment, and the practical operation clearance formed under the effect of temperature and load. Because the size of radial clearance directly affects the operating temperature, oscillation and service life of SKF Bearing, the detection of radial clearance of SKF Bearing is particularly important. How to measure the radial clearance of different bearings?
1. The radial clearance shall be measured by special instruments as far as possible. When there is no special instrument on hand, feeler gauge and other things can be used for measurement. When using the feeler gauge for measurement, it should be noted that the method before roller rolling from the feeler gauge shall not be used for measurement. When using manual measurement method, this method has high requirements for the measurer and is a method prone to fault, so it is generally not recommended.
2. As for SKF multi row bearings, the clearance requirements of each row are very high, so it is necessary to be qualified.
3. During measurement, ensure that the roller of the bearing falls into the groove bottom.
