“NISUKA” Shaft Mounted Speed Reducer is compact in design and optimum in performance.

A Shaft Mounted Reduction gearbox provides a very convenient method of reducing speed, since it mounted directly on the drive shaft instead of requiring foundations of its own. It eliminates the use of flexible coupling. These Gear Boxes are suitable for both forward and reverse motion.

A torque-arm anchors the gearbox and provides quick, easy adjustment of the V-Belts by means of its turnbuckle.

NISUKA Shaft Mounted Reeducation gearbox is manufacturing in EIGHT sizes, designated by N1 to N8. It may have two nominal gear ratios, 7:1 for N1 to N4 and 6:1 for N5 to N8. A very wide choice of final driven speed can be achieved by the use of an appropriate input V -Belt drive through various pulley combinations. The units will normally splash oil lubricated.Technical Specification

Taper Lock Bush and Support Bushes are manufactured from Special Steel to permanently remove any chance of corrosion in the future. The unique Taper bush locking system, which overcomes the difficulties, experienced with other methods of mounting, particularly in corrosive environments. Various sizes of Bores are available in the taper lock bush to facilitate easy mounting on different Shaft sizes.



Backstops (Holdback) are designed and incorporated to prevent reversal rotation or holding device to prevent reverse rotation in application such as conveyors, bucket elevators, fan, rotary pumps and kilns. Backstop are not recommend for use on system that are designed for handling Human such as elevators, man lifts, Sky lifts etc. Backstop cannot be used as a brake. The Backstop does not need additional lubrication as it gets oil from the gearbox.



Motor mounting options are available to fit directly onto gear unit through special motor mounting tools for shaft mounted gear unit. Motor mounting tools are designed with robust base plate which accommodates wide range of motor frame sizes. Each size of motor mount has sufficient adjustment to ensure that belt can be fitted and tensioned whenever required throughout life of belts.
