Industrial V-Belts Supplier

What are V-Belts

V-belts get their name from their trapezoidal shape, which helps them wedge into the sheaves. Twisted synthetic fibrous tensile chords, compressed by synthetic rubber, form a typical V-belt, rendering it strength and flexibility. There are Classical V-Belts, Wedge V-Belts (Narrow), Fractional Horsepower V-Belts (FHP), Branded Belts, V-Ribbed Belts, and Variable Speed Belts. HVH is an industrial V-Belts supplier, so you can check catalogs of different brands and find out the product you need.

Types of V-Belts

Classical V-Belts

Classical V-Belts are the most famous and most used around the world. They're also the oldest belts. They were invented in 1917 by Charles C. Gates. There come in W, Y, Z, A, B, C, D, and E sizes. W, Y, and Z sizes aren't used much in North America by the way. HVH Solutions is offering A, B, C, D, and E sizes of V-Belts. Classical V-Belts can work in poor conditions and can cover a load of up to 500 horsepower. They are also more economical than Wedge V-Belts.

Wedge V-Belts

The first Narrow belt (Wedge) appeared in 1959. The narrow design gives more support to the center of the belt and has a bigger contact surface with the sheave and allows for higher horsepower capability. There is no standard that was published by International Organization for Standardization for Wedge V-Belts. These are used only in North America. HVH Industrial Solutions offers a variety of Wedge V-Belts including Narrow V Belts, Narrow Cogged V Belts, and Narrow Combo V Belts.

Fractional Horsepower V-Belts (FHP)

This belt line exists only in countries that have adopted U.S. belt standards. FHP belts are identified as 2L, 3L, 4L, or 5L. These indicate the top width of the belt. These indications are the same as the classical W, Y, A, and B top widths respectively, although the FHP belts are a bit slimmer than the Classical ones. Although Classical belts can be used instead of FHP belts, the vice-versa doesn't work because FHP belts can't handle higher-horsepower applications. HVH Industrial Solutions offers 2L, 3L, 4L, and 5L FHP v-belts.

V-Ribbed Belts

A V-Ribbed Belt is a flat belt with corrugated driving surface ridges running longitudinally around the inside surface of the belt. They come in H, J, K, L, and M sizes. V-Ribbed belts are optimal for small-diameter sheaves. Better than industrial V-Belts in fact. Apart from being small sheave tolerance low mass and high elasticity of V-Ribbed Belts allow them to deal with reverse bending, high linear speed, and high-speed ratios. The H size is used in horizontal tub dryers, the K size is used in the automotive industry, and the rest (J, L, and M sizes) are used in any drives that use Wedge V-Belts or Classical V-Belts. HVH offers J and K sizes of V-Ribbed Belts.

Metric V-Belts

Metric V-Belts are narrow belts with a metric length measurement. These belts can generate 50-100% more horsepower than Classical V-Belts. These types of industrial belts come from Europe and bring with them European standards. Since European industrial companies have been expanding, their industrial machines created a demand for respective belts. That's what Metric V-Belts are.  HVH Solutions offers SPA, SPB, SPC, and SPZ types of Metric V-Belts.

Variable Speed Belts

These belts are used in applications where high heat and high-horsepower are important factors. Different speed ranges, like in fans for example, demand a belt that is wider and thinner than a standard industrial V-belt and can deal with a speed variation up to 10:1. HVH offers a range of Variable Speed belts.
