Spindle Bearing preferences

May 19 2010The twin row deep goove (or a twin row angular contact) will stabalise the spindle far better as it will not let the spindle deflect as much before the balls take up the axial loads If you have only a single row bearing see what can be done to fit a double row It

Double Row Angular Contact Bearing pre

Jul 31 2009Before I write off the use of double-row angular contact (DRAC) bearings in a project I would like to check with gurus in here first A standard DRAC bearing does not have internal pre-load so an external pre-load will render one row useless with its alpha facing the wrong way

Angular contact Ball Bearing

The preload can be built into the bearing or created when the bearing is inserted into an assembly The contact angle varies from 15 to 40 and is measured relative to a line running perpendicular to the bearing axis Angular contact bearings are unidirectional thrust bearings that can withstand heavy thrust loads and moderate radial loads
