Product Info Clutch
A mechanical element that transmits and blocks rotation between two power transmission shafts.
There are two types of lineup: cam clutches (one-way clutches) and SR clutches (single rotation clutches). Cam clutches have a mechanical non-backlash structure with many cams arranged between the inner and outer race, and are available for three different uses: backstop, overrunning, and indexing.
With a simple lever operation, the SR clutch can give a full rotation or an integer number of rotations from the continuously rotating outer race (drive side) to inner race (load side) with precise timing.

What is a Cam Clutch (One-Way Clutch)?
When it comes to mechanical one-way clutches, Tsubaki's Cam Clutch comes to mind.
This is a mechanical non-backlash one-way clutch with an arrangement of multiple cams.
The lineup is divided into three categories: backstop, overrunning, and indexing.
What is an SR clutch (single rotation clutch)?
The SR clutch is a clutch that, with a simple lever operation, gives one or an integer number of revolutions from the continuously rotating outer race (drive side) to inner race (load side).
The mechanism in which the inner and outer race mesh enables highly reliable and accurate timing drive that is not possible with clutches using friction mechanisms, ratchet mechanisms, or pin and key mechanisms.
Clutch product list
This clutch allows a simple lever operation to give one or an integer number of revolutions from the continuously rotating outer race (drive side) to inner race (load side).
SR series (indirect type)
Model number SR～
This model is adaptable to a wide range of usage conditions.
- ・Excellent responsiveness:
The inner surface of outer race (drive side) is full cylindrical, so when an ON/OFF command is given by the lever, outer race instantly
It is an extremely responsive mechanism that engages and disengages. - ・Reliable engagement:
The rollers are wedge-shaped and mesh between outer race and inner race, eliminating any slippage. - ・Stop position is constant:
The OFF (disengagement) position is always constant, so errors in the stopping position do not accumulate. - ・Excellent durability:
Torque is shared by multiple rollers, there are few parts that wear, and the high-precision finish ensures a long life.
You can look forward to it.
