The reverse installation will cause dynamic imbalance and affect the performance of the bearing.
Locking nuts or end caps are usually used for the axial positioning of ultra precision angular contact ball bearings on the shaft or in the bearing seat. These components require high geometric accuracy and good mechanical strength to provide stable support and positioning.
The locking torque MT of the precision lock nut or end cap bolt must be large enough to ensure that all components (including bearings) are positioned without deformation and damage.
When precision angular contact ball bearings are axially positioned using precision lock nuts or end caps, the following procedure should be used to ensure that all bearings are in place and that the locking force is reset to the level required for estimation.
Tighten the lock nut / end plate bolt to with a locking torque of 2 to 3 times Mt.
Loosen the lock nut / end cap bolt.
Retighten the lock nut / end cap bolt with the locking torque of Mt.
