Drawn cup roller clutches:

• are one-way clutches, which transmit torques in one direction ? Figure 1
• are available with or without an integrated bearing arrangement ? Figure 2, ? Figure 3 and ? Figure 4
• give very precise indexing
• allow high indexing frequencies
• have a low overrunning frictional torque
• are available with or without greasing
• are particularly compact in a radial direction and therefore permit extremely compact designs
• are suitable for housing materials made from steel, light metal or plastic
• can be combined with drawn cup needle roller bearingswith open ends HK and drawn cup needle roller bearingswith closed end BK
• have an extensive range of applications, for example as indexing clutches, back-stopping clutches and overrunning clutches ? Figure 1.

Product design

Drawn cup roller clutches are available:

• without bearing arrangement
  ? Figure 2
• with bearing arrangement (rolling or plain bearing)
  ? Figure 3 and ? Figure 4.

Drawn cup roller clutches

These drawn cup roller clutches comprise thin-walled, drawn outer cups with a series of ramps on the inside diameter, plastic cages and needle rollers, which serve as clamping elements. Steel or plastic springs hold the needle rollers in their clamped position. Drawn cup roller clutches can transmit high torques in one direction and are particularly compact in a radial direction. The roller clutches are available with and without support bearing arrangements.

Drawn cup roller clutches give very precise indexing, since the individual spring loading of the needle rollers ensures continuous contact between the shaft, needle rollers and ramps. They allow high indexing frequencies due to their low mass and the resulting low moment of inertia of the clamping elements. They also have a low overrunning frictional torque.

Drawn cup roller clutches can be used in various applications such as indexing clutches, back-stopping clutches and overrunning clutches. In these cases, the drawn cup roller clutch performs an overrunning or locking function.
