Recommended fits for the bore in housings to incorporate spherical plain bearings

The outside diameter of the spherical plain bearings series K is tolerated to h6. For series E please refer to each individual product page.

Recommended fits for shafts

The bore diameter of the ball of spherical plain bearings series K is tolerated to H7. For series E, G and W please refer to each individual product page.

Installation instructions

Attention: no tolerance or play can be allowed for the shaft when incorporated in the ball or the outer ring mounted in a housing. Through this is guaranteed that the glide movement arises on the nodular gliding surface only.

 

When mounting extra precaution has to be taken that the press force does not damage the bearing. The press force should not be initiated via the bearing itself. Thermal installation will reduce the necessary press force.

 

Axial locking of spherical plain bearings:

When under high static or dynamic axial loads, vibration, impacting load changes or high pivoting angles spherical plain bearings have to be locked axially.

 

Possible locking methods:

- locking through several punching points
- caulking of bearing on the housing through a flanging groove  
- with locking snap rings
- clamped with bushings on the facing surface of the insert
