Lower forces may be adequate or higher forces may be necessary depending on staking technique and axial load requirements. As a rule, only the amount of force required to get the desired amount of retention should be used.

The use of proper fits and staking techniques should not cause significant changes in bearing preload. As a minimum, the first and last article staked should be proof-tested. A method for proof-testing staked bearings for axial retention is shown below. This is the generally accepted method for checking retention that bearing and airframe manufacturers use. The graph below shows allowable design thrust loads for bearing O. The staking tool and staking anvil depicted below are made from tough, hardenable tool steel for example, A-2 and heat treated to R c 55 to The critical dimension of the tools are as listed.

As a final check on the staking tool and anvil, a final layout drawing should be made to check fit-up.

New Hampshire Ball Bearings, Inc. NHBB is a leading manufacturer of precision bearings and complex bearing assemblies for the global aerospace, defense, medical, and high technology markets. The company is a subsidiary of MinebeaMitsumi Inc.

Staking Procedures Staking is a method of installing a bearing with a V-groove into an assembly or housing. V-Groove Staking Procedure Install bearing into housing and position it symmetrical about housing centerline within.

Mount bearing and top anvil over bottom anvil guide pin. V-groove staking method A trial assembly should be made for each new bearing lot to determine the staking force necessary to meet the axial retention load required.
