Reference Model CSK  
Type CSK is a sprag type freewheel integrated into a 62 series ball bearing(except sizes 8 and 40).

Including: CSK8(KK8 BB8) CSK12(KK12 BB12) CSK15(KK15 BB15) CSK20(KK20 BB20) CSK25(KK25 BB25) CSK30(KK25 BB25) CSK35(KK35 BB35) CSK40(KK40 BB40).

It is bearing supported, delivered grease lubricated and protected against dust of more than 0, 3mm. The use of additional "nylos" type seals is recommended especially when the working temperature exceeds 50° , COil bath lubrication is also possible. All the CSK versions are equipped with "formchromed" sprags. This process increases several times the overrunning life time. 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. Please contact us when either the ambient orthe operating temperature is not within the range +5° , C to +60° .

CSK. 2RS is 5 mm widerbut is equipedwith lip seals to be water splash resistant.
