Roller bearing AS20
Description
1.WAS is a sprag type freewheel supported by bearing, its construction is same as our WOK,good mobility and lower noise than As roller type freewheel.
2.Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation.
3.Nominal outside dimensions are the same as series 62 ball bearings.
4.A typical arrangement is to install this type alongside a series 62 bearing, within the same location tolerance, as shown on the following page.
5.The inner race is keyed to the shaft (except 6mm bore).
6.The outer race has a positive N6 tolerance, to give a press fit in a H6 housing. The inner race can be pressed on a shaft to K6 tolerance.
7.The outer housing must be strong enough to not expand after assembly.
8.The design can accept an axial misalignment of inner and outer race. of±S2.
