The manufacture of bearing inner sleeve

After grinding inside and outside diameter coarse grinding inner raceway diameter raceway grinding (branch), coarse grinding inner raceway requirements similar to coarse grinding outer raceway. After coarse grinding inner diameter, the advantage is to have inner diameter, inner raceway and inner diameter of concentric, reduce product bearing vibration and noise. After coarse grinding inner diameter inner raceway grinding and its requirements and the outer raceway grinding is similar. And then to carry on the fine grinding inner diameter, lapping inner raceway (similar to lapping outer race).

Bearing assembly surface and cooperate with the surface of the parts, if there is any collision, rust layer, abrasive dust, sand, dust and dirt, a bearing installation difficulties, cause assembly position is not correct; Two of these attachments form abrasive, easy to scratch non-standard bearing working surface, affect the assembly quality.

Therefore, before the installation, should axis neck, the surface of the bearing shell hole, shoulder end face, and connecting parts such as bushings, washer, end with the surface, a careful inspection. If there is any rust layer, usable fine file file, fine cloth, at the same time also want to clear the attachments on the surface of bearing assembly and connection parts.Inner and outer separable bearing, don't put the quality of outer ring exchange mistake so as not to affect the contact each other.

Of non-standard bearing, and may not arbitrarily put out the rolling element bearing mix, in order to avoid the installation location disorder affecting accuracy. Installing a bearing, for ease of review the bearing code, not wrong, it should be literally put out and installation of bearing ring.
