1、WAS is a sprag type freewheel supported by bearing, it’s 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±S／2.
2)Inner race overruns
3)Outer race overruns
Standard installation of WAS is put the clutch with the bearing side by side,with same position,with the same tolerances.Use splined to couple the inner ring and shaft coupling.The outer sides of the end face of the key for securing the outer wall With the machine to transmit torque
Use 2 # lithium grease 30% + Engine oil 70% , Stirring evenly. The grease required temperature range -40 ℃ ～+ 150 ℃. Plus grease once for every month.
