Free Wheel Clutches

V W Impex offers Free Wheel Clutches, CSK Series (one-way bearing). The CSK model freewheel is a sprag type clutch integrated into a 6200 series ball bearing (except sizes 8 and 40), which provides a one way clutch. The freewheels are directional couplings, which means that the driving member rotates the driven member in one direction, while automatically disengaging itself from the driven part when the direction of rotation is reversed. The two operating states are transmission of torque and idling (overrunning). Type CSK is a sprag type freewheel integrated into a 62 series ball bearing (except sizes 8 and 40). It is bearing supported, delivered grease lubricated and protected against dust of more than 0.3 mm. The use of additional "Nylos" type seals is recommended especially when the working temperature exceeds 50°C. Oil bath lubrication is also possible. All the CSK versions are equipped with "Formchromed" sprags. The 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.

V W Impex is an established name in the field of bearings as an importer, exporter and supplier of eccentric bearings, precision bearings, linear motion guides and rails, ceramic bearings, plastic bearings, and above all Nilos rings. Backed by an experience in this field of over two decades, the company imports directly from manufacturers in Germany, England and USA, a range of hard-to-find bearings not available in the Indian market.
