Drawn cup needle roller bearing - OD : 4 - 30 mm (1/8 - 1")
Drawn cup - roller clutches form tools that can help in transmitting torque between housing and shaft in a particular direction. They also provide free overrun in opposite direction. They make use of smaller radial - section similar to that of drawn cup - needle roller - bearings. They can be used for operating directly over the hardened shaft and are light weighted and compact. There is a simple - press fit in housing which enables them to be installed easily. They are available either in the units of clutches or as assemblies of bearings and clutches. Both these forms can have metric and inch nominal series. They can be used with bores of size ranging from 4 to 30 mm. At the time of torque transmission either housing or shaft can act as input member. Rollers usually wedge against the interior ramps for positive transmission of torque. Transition to lock from overrun can happen with minimal loss of motion.
