1.One way bearing WOK20(CSK20.BB20.KK20) is a sprag type freewheel,also named CSKBBKKOW etc.,it intergrated into 6203 series ball bearing.It is bearing supported, delivered grease lubricated and protected against dust of more than 0.3mm.The use of additionalnylos type seals is recommended especially when the woking temperature exceeds 50.
2. Oil bath lubrication is also possible if the original grease is first flushed out using s suitable solvent.
3. Torque transmission is ensured by a press fit assembly into a rigid outer housing with N6 tolerance. and onto a shaft with n6 tolerance. The initial bearing radial clearance is set at C5,and is reduced if using the press fit as specified.
4. The sealing in the both side of inner race or outer race is assembled into the inner race by a taper. So it improved the hermetic sealing and fastness, togther raised the work efficiency.
5. If not fit assembly, giving a WOKPP series C3 bearing clearance will be necessary.
6. WOK-2RS is 5mm wider but is equipped with lip seals to be water a splash resistant.
7. WOK..P is a sprag type freewheel integrated into 62 series ball bearing (except size 40).In addition to the basic WOK model, type WOK..P features a keyway on the inner race. For this reason it can be keyed to a shaft to K6 tolerance. The outer race must still be pressed into a rigid housing to N6 tolerance.
8. WOK..PP series features a keyway on both the inner and outer race .The recommended mounting tolerance are K6 on the shaft and K6 in a rigid housing .A H6 tolerance on the shaft or H6 in the housing are also acceptable for a slight fit assembly.
9. Operating temperature range;-40 to+100.peaks up to+120 are acceptable for short periods.
