Installation dimensional accuracy of outer spherical bearing seat

Pay attention to installation reaction. If the raceway shows the spacing of the pit, it indicates that the load has passed the elastic limit of the raw material. This is due to static data truncation or more serious impact (such as the installation of a small axe hammer hit the outer spherical bearing seat, etc.) caused. The installation method of the outer spherical bearing seat is to act only on the ring ring to be riveted.

Pay attention to the installation orientation of the outer spherical bearing seat of the thrust self-aligning roller. The outer spherical bearing seat has an egg ring contact zone and only diligently bears radial thrust in one side. When the outer spherical bearing seat is installed at the relative orientation, the bearing steel ball is at the edge of the raceway, and the supporting surface will germinate trough wear belt. Due to these in the installation to pay attention to the exact installation orientation.

Outer spherical bearing seat

Specification precision of outer spherical bearing seat for thrust self-aligning roller (new project related to shaft and housing installation) :

1. Inner diameter. The tolerance error of the total width of the outer spherical bearing seat and the total width of the installation;

2. Allowable error of inner and outer compound circle diameter of outer spherical bearing seat of roller group;

3. Allowable boundary value of fillet outer spherical bearing seat specification;

4. Allowable variation of total wide outer spherical bearing seat.
