Ball bearing - Wikipedia

In a deep-groove radial bearing, the race dimensions are close to the dimensions of the balls that run in it. Deep-groove bearings support higher loads than a shallower groove. Like angular contact bearings, deep-groove bearings support both radial and axial loads, but without a choice of contact angle to allow choice of relative proportion of these load capacities.

How are bearing stiffnesses calculated in MASTA? – SMT

2/8/2016· How are bearing stiffnesses calculated in MASTA? Bearing Analysis. For rolling bearings, the stiffness is derived from nonlinear load deflection models using Hertzian contact theory and bearing internal geometry. This calculation is done in 5 dimensions (3 translations and 2 tilts) so the result is a 5×5 stiffness matrix for a particular load.
