Ball Bearings and Miniature Bearings: Dynaroll - Recommended Bearing Shaft and Housing Sizes and Tolerances

RECOMMENDED FITS. The following table shows recommended shaft and housing sizes and tolerances for different appliions. It is assumed that bearings used are ABEC 5 tolerance (+0 -.0002 inch) for bore and O.D. If a different grade of bearing is used, this will affect recommended dimensions of mating components.

Polymer linear bearing grooves | Physics Forums

22/12/2021· My guesses are; 1. Slots are there to provide a path for dust, dirt and wear particles to escape the system. But they seem to be much too big for that. 2. Polymers tend to have large coefficients of thermal linear expansion. The sectional area is more critical. Without some space, pressure would increase when the bearing material gets hot, so
