One Way Needle Bearing Drawn Cup Needle Roller Clutches With Steel Springs
Drawn cup roller clutches are one-way clutches, the name of which
is derived from the thin-walled, drawn outer rings (cups). They can
transmit high torques in one direction and have an extensive range
of applications, for example as indexing clutches, back-stopping
clutches and overrunning clutches.
Due to their design, drawn cup roller clutches have a very high
indexing accuracy, a high indexing frequency and a low overrunning
frictional torque.
In order to guarantee concentricity and, as a result, correct
functioning, a support bearing arrangement is necessary for drawn
cup roller clutches. Drawn cup roller clutches are therefore
available with an integrated bearing arrangement (HFL). For drawn
cup roller clutches without an integrated bearing arrangement (HF),
the support bearing arrangement must be provided by additional
rolling bearings.
Drawn cup roller clutches are available with or without knurling.
They are supplied greased as standard. For applications with oil
lubrication, drawn cup roller clutches are available without
greasing.
