Kavitsu manufactures and supplies shaft mounted speed reducers and allied products. It has over 10 years of experience in this field. The speed reducers use hardened and profiled helical gears for smooth operation, high efficiency, and long life. They have heavy duty roller bearings and enhanced seal options. The housings are made of close grain graded cast iron or cast steel depending on the load requirements. Heavy duty input shafts made of high tensile alloy steel are suitable for all overhang load conditions. Torque arm mounting positions are provided for universal mounting depending on the output shaft rotation direction. Selection charts are provided for different models showing their specifications and maximum power handling capacities for various input RPMs and gear ratios.

HOUSING
Close grain Graded cast iron for light duty gearboxes & cast steel for heavy duty gearboxes
are the material used for significant loading conditions.
SHAFTS
Heavy duty input shaft manufactured in High tensile alloy steel, suitable for all overhang load
conditions; a proper thought is given for bending and tensional stresses.
TORQUE ARM MOUNTING :
Two positions are provided as per direction of rotation of output shaft for the mounting of
torque-arm to have an advantage of universal mounting.
