2873-LH Overrunning Roller Clutch

The Tiny-Clutch 2873-LH overrunning roller clutch is a miniature roller and cam type one-way clutch from our D-Series line of clutches. The D-Series clutches are most frequently used to allow a driven member to overrun the input, or for backstopping a load, they can also function to convert oscillating motion to rotary motion. These clutches use our proven cam and roller principle for long life with trouble free performance. The cam, housing and rollers are made of hardened steel and each roller is energized by a spring which is held square and centered in a drilled pocket. The design of the clutch allows for near zero backlash as well as high free-wheeling speeds. The clutch will not jam in the free direction. The 2873-LH overrunning roller clutch is based on our D93A roller clutch. The knurled hub on the housing allows installation of a pulley, gear or sprocket. This clutch drives counter clockwise and slips clockwise, has a 3/8 inch (9.5mm) bore, the cam is screwed and/or keyed to your shaft, and power may be applied to the clutch through either the housing or the cam. These clutches can be used for many different applications and are the original equipment clutches for multiple brands of hot stamping machines.
