Shaft Mounted Speed Reducer (SMSR) Manufacturer India

Shaft mounted speed reducer SMSR gearbox by Kavitsu

A shaft mounted speed reducer (SMSR) slides directly onto the driven shaft through its hollow output bore and is held by a torque arm. No foundation or output coupling is needed. The motor usually drives it through V-belts. Kavitsu Transmissions manufactures SMSR gearboxes in Satara, Maharashtra, in both square and round housing shapes.

SMSR gearboxes are a simple, economical choice for conveyors, crushers and screens, where quick installation and easy belt-based speed adjustment matter.
