Belt Section	Pitch in mm (P)	Thickness in mm (T)	Maximum Nos. of Ribs / Sleeve	Function
H	1.6	2.9	24	Fractional Horse Power for very light duty applications
J	2.34	3.8	96	High linear speed up to 60 m/s in “J” section, Low cost for light duty applications
K	3.56	4.5	24	Designed specifically for the automotive industry, it is also suitable for Machine Tools drives etc
L	4.7	7	50	Medium duty drive covering a wide range of applications
M	9.4	13.5	40	High performance makes it unrivalled for heavy duty applications

Groove Dimensions as per ISO 9982 /DIN 7867

Compact Drive - Poly V Belt Pulley can be used with smaller pulley diameters to give a lighter and compact drive
Single Belt - Always single belt is used which avoids any problems arising out of length differences and single belt can drive several accessories
Reduced Diameter - Diameter upto 9mm with the “H” profile, compare to 50mm with V belts
Reduced Belt Width & Length - Belt width & length can be reduced for a given geometry and the same power transfer
Reduce Consumption - It reduces consumption due to higher output
Higher Power - In compare to conventional V-belt pulleys, it consumes 40% high electric power per unit
Zero Slippage - It eliminates slippage due to maximum wedge contact on the pulleys
Higher Bearing Life - It gives higher life to bearings due to lesser static tension
Silent Drive - Low Noise and Vibration free without generating heat in every application
Higher Speed - Very High Power Transmission Ratio 1.60 v/s 1.20 in V-belt pulleys, it can be used at higher speed more than 40m/sec.
Facilitate Machining - It can be used on smooth pulleys i.e. receivers pulleys, There is no need for matching belts and it extends life span

Application of Poly V Pulleys ( Poly V Sheave Pulleys / V Belt Groove Pulleys) :

Engineering :
- Machine Tools : It is used in CNC Milling & Turning Machines to operate high speed ratio at small diameter, to enhance surface finishing, to avoid vibration
- Heavy Industries : Hammer Mill and Extrusion Press where power consumption is high upto 600 kw by using single belt which requires greater machine efficiency.
- Drilling Equipment, Industrial Saw Mill to use high torque transmission and avoid vibrations

Refrigeration Systems :
- Industrial & Vehicles Air conditions : Consistency in Structure, Energy Efficient, Easy to drive compressor as an option
- Freeze container : It increase operating life, Its compact drive can reduce diameters and width of pulleys
- Centrifugal Fan : It can be used due to high abrasion resistant, to increase the possible ratio 1.6 and flat driven pulley at ratio > 4
- Air compressor : It increase output, consumes low electricity, low noise and maintenance

Food Processing Machinery : To avoid functional slippages under jam conditions used in Food processing mixer & pump, Flour Mill, Bread Making Machines, Ice-cream and Coffee Machine etc
Roller Conveyor : It can perform high to transfer light, medium and heavy load (from 400 kgs to 2mts)
Constructions : Concrete or Cement mixers, Thermal Engines, Cranes, Excavator, Vehicle engines, Saw Mills (cutting stone or metal sheet), Steam Roller etc.
Agriculture & Gardening : Modern equipments in Cultivation, Harvesting, Collection of crops like Tractors, Food Grinding Machineries, Lawn Mover machines, Scrub cutter, Stone Crusher, Vegetable Crushing machines, Spraying equipments etc
Power Generation : Wind Turbines, Generator, Mini Hydro Power plant
