Processing features of FAG rolling bearing parts

In comparison to the common mechanical parts, FAG bearing part is the short and thin rotary surface body. The rotary body determines simple processing machine tools, most of which are lathes and grinders. The short and thin imply the good axial stiffness and the axial deformation can be neglected. It also means the poor radial stiffness and intensify method in procession should be considered specially.

With the simple structure, rolling bearing parts require the the high-standard technology. The processing features are as follows:

1、precise processing

The surface of most bearing parts need to be grinded. The grinding size and geometric accuracy are in μM unit, especially rolling raceway and rolling body of bearing ring need super-processing and super-lapping.

2、multi-operation processing

The high requirement of bearing parts leads to numerous of production procedures. The common bearing needs 20-40 procedures, even 70 procedures.

3、forming processing

The working surface of bearing parts is rotary forming surface and it is suitable to be processed in forming method. For example, the forging rolling and grinding of rolling raceway of bearing ring are all peocessed with forming cutters and boards.

Besides, most bearings are standard products and the same mode is largely needed. To inprove productivity and decrease cost, lots of bearing manufacturers carry out mass production according to its model and variety.
