Four
Jun 25 2015A four-point contact ball bearing can accommodate axial loads in both directions in combination with radial loads up to a certain level and provides a very tight axial shaft position tolerance The bearing also saves space because it can be seen as the combination of two single row angular contact ball bearings into one
Contact mechanics
Contact mechanics is the study of the deformation of solids that touch each other at one or more points A central distinction in contact mechanics is between stresses acting perpendicular to the contacting bodies' surfaces (known as the normal direction) and frictional stresses acting tangentially between the surfaces This page focuses mainly on the normal direction i e on frictionless
