Lack of some operators to identify the experience of the rolling bearing, as long as see the rolling bearing no obvious damage will continue to use, so that cause serious failure later.Also somebody just remove the rolling bearing, without check and replace, sometimes can continue to use of the bearing is changed.Rolling bearing technology condition should be check on dedicated tester, also can use dial indicator for some data measurement.But for general operator, when does not have these conditions, can roughly check experience way.
1) the method of observation.Rolling bearing with the naked eye observation, inner and outer raceway should not crumbling and serious wear and tear, and in a circular groove;All roller surface should be no spots, cracks and peeling now;Cage should not loose, without damage, did not wear out, and the roller clearance but big.
(2) handle.Normal inner and outer race and rolling elements of bearing clearance is 0.005 ~ 0.010 mm.For a phase of the rolling bearing has been used, with inner race for the axial shaking fingers clench, should have no obvious kuang dynamic noise.
(3) the rotation method.With one hand holding the bearing inner race, another hand rotating seat, bearing should be flexible rotation, and should not feel radial shaking.
Check, should combine the above 3 kinds of methods, to facilitate the technical state of rolling bearing to make the right judgment.For tapered roller bearing, still should observe whether rolling body is located in the middle of the outer race, if you have moved forward, should be less than 1.5 mm.
