Drawn cup roller clutches NSK RC121610

Roller couplings with stamped outer ring:- one-way couplings that transmit only torque in one direction, so they must be used on the same shaft with rolling or sliding bearings that will take the radial load,- available with or without integrated bearing unit,- give very accurate indexing,- allow high indexing frequencies,- have a low overrunning moment of friction,- available with or without lubrication,- are particularly compact in the radial direction and therefore allow extremely compact designs,- suitable for housing materials made of steel, light metal or plastic,- can be combined with drawn cup needle roller bearings with open end HK and closed end BK- have a wide range of applications, such as indexing clutches, reverse stop clutches and freewheelsThey consist of thin-walled, stamped outer rings with a number of inclined sections along the inner diameter, plastic cages and needle rollers that serve as clamping elements. Steel or plastic springs hold the needle rollers in the clamped position. Roller couplings can transmit high torques in one direction and are especially compact in the radial direction. Roller couplings are available with and without support bearings. The correct operation of such couplings can only be guaranteed if the alignment error between the support bearing and the shaft can be kept low,
