Types B200 & B500

B Series clutches are designed primarily as backstops for gearboxes, but have also been used for indexing in the textile industry. The clutches operate directly on customers' hardened and ground shafts. They consist of a plain outer race with key to locate in housing, and a full complement of sprags activated by two garter springs. The outside diameter is the same as 62 series ball bearing enabling simple fitting beyond the bearing on intermediate or output shafts of gearboxes. Bore sizes range from 16.5 mm to 56 mm for operation alongside bearings 6203 to 6210. Torques up to 1700 Nm can be restrained.

*Types CNAS and CNFS Roller Ramp Clutches*
Types CNAS and CNFS freewheels are light duty roller ramp clutches manufactured to standard bearing dimensions; CNAS type as 62 series ball bearings and CNFS type as NU 23 roller bearings. The clutches are mainly used for precision indexing and overrunning

applications. Torque transmission is via a key on the shaft, and for type CNAS a press fit of outer into housing, and type CNFS via two keys in the end face of the outer race.


*Types CKK & CSK Sprag Clutches* Clutch types CKK and CSK combine individually sprung sprags with a deep groove ball bearing to provide a compact, low cost high torque freewheel. Used for backstop and overrun applications, these clutches provide the ideal, low cost, solution where space is restricted. Type CKK clutches are manufactured to the same specification as 62 Series ball bearings (except CKK 8) enabling direct interchange. Type CKKN clutches have inner race keyseated to DIN 6885 sht. 3 (except CKKN 40) to enable torque transmission by key. Clutches can also be provided to order with keyseat on outer race (Type CKKNN).
Type CKK-RS and CKKN-RS are fitted with metal shields and '0' rings to retain lubricant and exclude dust, for applications where relubrication is impractical or units running at higher temperatures. Type CSK-RS has extended width races to enable fitting full rubber sealing discs, making them ideal for dusty applications. These units can also be supplied to order with inner race keyseated (Type CSKN-RS).
