Self-aligning roller bearing quality acceptance standard

Wafangdian bearing - Bearing - comfortable and durable On June 27, the authors explain for you: spherical roller bearing quality acceptance standard 1, assembly good bearing face, should with the shoulder or hole of shaft surface abutting, bearing specifications should face outward. 2, should guarantee the bearing is installed on the shaft and the bearing hole, not skewed and jam phenomenon. 3, rolling bearing working in order to guarantee a certain room for expansion, and in the two coaxial bearing, must have a coat can be generated during thermal axial movement, in order to avoid the shaft or the bearing due to there is no room for the additional stress, fever and was burned down sharply. 4, the bearings must be clean, strictly avoid steel, iron and debris into the bearing internal. 5, bearing the coat after assembly shall not be loose, should be 0. 01 ~ 0. Tension force of 3 mm. After 6, assembling, bearing operation should be flexible, no noise, working temperature should not exceed 70 ℃. Self-aligning roller bearing quality acceptance criteria: the various parts of the bearing clearance should comply with the requirements. Assembly should be done after the work of checking and heat gap adjustment, general work should reach the level of flexible rotation, temperature gap should conform to the requirements of the axial clearance of all kinds of bearing, and can take swimming end bearing or to control the thickness of the end cover gaskets, with 0. 25 ~ 0. 5 mm axial clearance.
