30 Series (Asymmetrical)


The Comet 30 series clutch is desirable in applications requiring extra rugged driving ability.

The model 30 uses a ¾” top width belt. The belt mass in the 30 series is desirable in applications requiring extra rugged driving ability, such as dune buggies, go-karts, mini-bikes, ATV’s, grounds maintenance equipment, materials handling devices and industrial equipment. The 30 series is mounted with both stationary sheaves inboard. Mounting can be on a flat, fixed plane, requiring only minimum displacement.
