Salient Features of Variators :-

Speed Variations : By feeding fixed speed to Variator, stepless speed variation can be obtained from
Max. speed = 1.7 x Input speed to
Min. speed = 1/7 x Input speed
Max. speed = 12 : 1 to 3 : 1 depending upon selection
Min. speed

Torque Multiplier : When speed is reduced, variators can replace Gear Boxes.

Speed Multiplier : Upto 1.7 times input speed without necessity of speed increasing gear.

High Output Torque : Over Load Capacity : Upto the standstill of an electric motor of the same power acting as a mechanical clutch.

High Efficiency : Overall 85% throughout full speed range, idealy used for constant power transmission applications in all types of Industries.

Speed Holding : Quite stable with uniform load and within 0.25% with Max. Load.

Reliability : Drive is highly reliable with long life as load is equally distributed on number of conical Rollers which are hardened and ground to close tolerance.

Simple Design : Can be attended by skilled fitter as no electronic/electrical parts/circuits are involved.

Compactness : High Power Transmission capacity with small dimensions.

Speed Control : Quick and simple. By rotating control knob, in running condition only.

Free From Noise and Vibrations : No moving parts like Chains, Belts, etc. Drive is through rolling action of PRECISION ROLLERS which are continuously lubricated. All components are well balanced.

Totally Enclosed Unit : Ideal for hazardous zones.

Maintenance : Practically maintenance free. Only ensure proper lubrication.

Colinear Input & Output Shaft : In-Line Input and Output Shafts.


Special Features :

Variator with extended output shaft and additional roller bearing is specially designed to couple with V-Belt and Pulley. The extended shaft with an added bearing has the advantage of controlling the tension uniformly on both bearings.

In the standard Variator, when the output shaft is coupled with the V-Belt and Pulley, the tension results on one side.
