Primary stock in the excellent Medway brand. 4L Section Wrapped V-Belts with a coloured dry cotton cover, the belts have a large diameter of ARAMID (Kevlar) cords, impregnated with special compound which eliminates the need for re-tensioning and offers High Tensile Strength along with non-extensibility and a high resistance to shock loads. The belts are covered with a double wrap of special fabric to ensure high resistance to wear and tear and reduced slippage while clutching. Manufactured as part of an extensive range of specially constructed belts tested and approved to suit many OEM specific applications with attractive aesthetic qualities - coloured "dry cotton" - type wrap is synonymous with the belts used by major quality OEM machine manufacturers. In the unlikely event that we should not have Medway stock available then a quality brand will be supplied.

Kevlar fiber belts are made with high-strength fiber cords for heavy duty applications and severe duty cycles. these belts have a “drier” cover fabric that was designed to increase flexibility and withstand severe clutching action, bending or twisting, heavy loads and backside idler applications. Kevlar fiber belts are oil and heat resistant.this kevlar construction is also used in military armor and bullet proof vests. As your stock belt wears down, it gets thinner and thinner. this, in turn, will start to decrease your top speed. A kevlar belt will keep this from happening
How can i get the longest life out of my v-belt?
Proper Tension: is often overlooked. All belts need to be tensioned when first installed, but they stretch dramatically during the first 24 hours of operation and lose their tension. This can cause them to squeal and can rapidly lead to sheave wear. Proper maintenance includes tensioning the belts at regular intervals throughout their life. New belts are available for high-power and hvac applications that are more stretch-resistant; contact our sales personnel for more information.
Worn Pulleys: can be a source of rapid belt wear. When tension forces a v belt to conform to a worn sheave wall, the belt runs hotter and its life will be shorter.
Misalignment: will lead to uneven wear. the belt should enter and leave the sheave groove in a straight line, or else the sides of the belt will wear out very quickly as they scrape against the sheave edges. Eventually, this can cause the belt to flip over in the groove, which will destroy it. usually, sheaves can be aligned by using a straight-edge against the outer faces; for long-center drives, there are laser-alignment tools available.
