拖拉机上有90%的轴承,只是由于磨损后产生过大的间隙而不能继续使用。只顾将轴承的使用期限延长,继续使用间隙过大的轴承能引起整个部件工作条件的恶化,缩短部件上各零件的使用期限和加速轴承的损坏。但如果滚动面和滚珠的的状态良好,将轴承的间隙缩小,这样轴承还可以使用一个 Tractors have 90% of the bearings, just because of excessive wear and tear after the gap can not continue to use. Just to extend the service life of the bearing, continue to use the bearing is too large gap can cause deterioration of the working conditions of the entire component, shorten the parts of the parts on the life and accelerated damage to the bearings. However, if the rolling surface and the ball in good condition, the bearing clearance reduced, so that the bearing can also use a
