Drawn Cup Roller Clutches

INA from Schaeffler drawn cup roller clutches are one-way clutches comprising thin‑walled, drawn outer rings with a series of ramps on the inside diameter. There are also plastic cages, pressure springs and needle rollers. They can transmit high torques in one direction and are compact in a radial direction.

Drawn cup roller clutches give 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.

Features and Benefits

• Lower operating costs

• Reduced maintenance due to improved lubrication

• Lower heat generation

• Less noise

• Roller clutches, HF series, do not have a bearing arrangement and can only transmit torques

• Roller clutches, HFL series, have an integral plain or rolling bearing arrangement and can support torques and radial forces.

Product Application Information

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.
