Poly Vee Belt Drives

A Poly Vee Belt Drive utilizes the benefit of a single flexible high power capacity low stretch belt with a continuous cord across the full width of the belt enabling a reduced belt width and smaller pulley diameters which in turn allows for higher belt speeds and higher transmission ratios in smaller spaces.

Some of the other Benefits of a Poly Vee Belt drive:

The Poly Vee Belt drive employs the incompressible fluid characteristics of rubber componds to distribute pressure evenly over all parts of the driving surfaces. Unlike Vee / Wedge belts which wedge into the grooves and require clearance beneath the belt to acheive the action, the Poly Vee belt does not operate by a wedging action, but is made for the closest possible fit into the pulley, with substantially continuous contact between the ribbed surface of the belt and the pulley grooves, ensuring:-

1. Reduced losses due to bending
2. Smooth running - constant pitch diameter
3. Maximum frictional grip
4. Minimum power loss due to centrifugal force

Poly Vee Belts H, J, PK, L & M Sections:

Although the full range of Poly Vee Belt are available in five pitch sizes as follows, our current stocking ranges cover the main sections used for industrial application J Section (Light), L Section (Medium) with the M section (Heavy) being available on a to order basis.

H - Extra light duty belt for volume applications in small high-tech electrical equipment. ( Available on Request)

 J - Low cost space saving belt for light duty applications. (Available from UK Stock)

PK - Specifically designed for the automotive industry, but also suitable for special industrial drives in the machine tools industry. (Now Available on a short Lead Time from Factory Stocks)

L- Versatile medium duty belt for a wide variety of industrial applications. (Available from UK Stocks)

M - Heavy duty belt for unrivalled performance. (Available on Request)
