Double Angle V Belts: Sections AA,BB,CC
 
Designed specially for reverse-bend serpentine drive. New cross section for maintaining proper belt position in pulley groove even in case of extreme reverse-bend drive. Larger flexibility gien by as well as to NEW CROSS Section, the service life has become longer than that of traditional double V-belts.

Wedge V Belts: Sections 3V,5V,8V
 

Higher HP power rating. Requires about 33% of the space needed by classical V-belt drive. Long Life. High efficiency. Heat and oil resistant.  Belts are anti-static. V-belts for multiple drive retains superior uniformity under tension. A matched set remains perfectly matched even after long period of storage.

Variable speed V-belts, also termed V / S - belts, are temperature and oil resistant as well as anti-static. A special rubber compound with textile fibres oriented across the length of the belt provides high stability and minimizes deflection in the cross section. The moulded cog ensures maximum flexibility and optimum fit in the pulley grooves. The cord, the power transmitting element, has been designed for heavy power transmission while at the same time ensuring a very high degree of length stability. Special belts are produced to order, e.g.with Aramid cord .

Classic Cogged V Belts: Sections 3VX,5VX,AX,BX,CX

Cut edge moulded cogged V-belts have a precision cogged profile base which is designed for uniform stress distribution and superior heat dissipation. Their construction permits greater flexibility and a higher kilowatt capacity for exceptional performance on small diameter pulleys using FHP, Classical, Wedge and Narrow section drives. The robust construction is specially designed to fit the pulley grooves exactly, which allows maximum wedging action. The belts are built with low stretch-high modulous stiff polyester tensile members to resist fatigue and shock loads. The cord and polychloroprene rubber are bonded to prevent separation and reinforcement layers on both sides of the tensile member improve cord stability. All belts are oil & heat resistant.

Kevlar® corded belts, also called Aramid or extra-heavy duty belts are constructed of organic polyaramide fibers that are manufactured using complex chemical processes. **Interesting fact: Kevlar® is the same material bulletproof vests are constructed with.  Kevlar belts are designed for lawn mowers, tillers and any other clutching applictions.
 
Features and Benefits:
Large Diameter ARAMID cord impregnated with special compound eliminates the need for retensioning while offering:
 - High Tensile Strength
- Non-extensibility
- High Resistance to shock loads.

Double wrap of special fabric ensures:
- High resistance to wear and tear.
- Reduced Slippage while clutching.

Belt Characteristics ensure:
- High resistance to repeated reverse flexing
- High resistance to oil, heat and cracking.
