A contact analysis for unconventional mounting processes of angular ball bearings
International Journal of Mechanics and Materials in Design, 2023 AbstractRigorous protocols must be followed when mounting ball bearings to avoid structural damage and subsequent malfunctioning or unexpected failures. Unconventional mounting procedures may produce excessive contact pressures between the elements of the bearing, therefore the whole process must be well-understood and modelled to prevent unwanted ...

Pivoting and Slip in an Angular Contact Bearing [PDF]
A S L E Transactions, 1984 Pivoting slips are calculated for the ball-race and ball-ball contacts in a retainerless bearing. The calculation is kinematic, ignoring all inertial loadings. Pure spin and uniform precession of the balls are considered. Pivoting slip magnitudes are compared with several other kinds of slip which were previously reported in an R4 size bearing ...
