The v-belt is based upon the principle of a wedge shape and compression to transmit the HP and Torque. It's design is in the shape of a "V" with a pre-determined pitch line usually made up of nylon tensile members to transmit the HP and Torque required. The v-belt is used in applications where HP or torque must be transmitted between a driver (usually an electric motor) and a driven piece of equipment, such as a blower for an air handler, conveyor, or mixer.

The most popular series of v-belts are "Classical Drive Belts" A, B, C, D, E cross sections, the "FHP series" 3L, 4L, 5L cross sections, and the "358 series" 3V, 5V, and 8V cross sections. These three series of belts can be applied to almost any application requiring the transmission of HP and Torque. The classical and 358 series belts are available in multiple v-grove combinations.

A belt could also be used to convey material across the top of the belt such as on a belt conveyor. You would typically find this type of belt on any material handling applications including rock and sand, bakery goods, most assembly lines, and/or packaging lines. The conveyor or flat belt, as it is known, comes in many, many different styles, widths, materials, and compositions.

We also have "gear belts" which are also known as "positive drive belts" because the teeth in the belt mesh with the teeth in the pulleys, thus creating a positive drive. These are usually found on timing applications or in drives requiring a higher HP or Torque capacity than v-belts will accept. The teeth do not allow the belt to slip or rely on the wedge or compression principle to transmit HP or Torque.

There is also link belting which incorporates either metal tabs that piece the belts together or the belts with hooks on them that twist the pieces together making them useful in quarter turn drives or non-adjustable drives. They are also used in emergency situations in place of standard v-belts.

The next type would be the poly-v drive belt which has ribs designed into the belt’s inside circumference that act as miniature v-belts in their transmission of HP and Torque. These are also called serpentine belts and are used in multiple shaft applications, where you need multiple shafts turning the same and different directions, all on the same drive. The most known application would be the drive belts used on most of the newer automobiles.

Some of the belts we carry are listed below:

Banded, Conveyor, Endless, Flat, HTD, Metric, Plastic, Timing, Twist Link, V Type, Variable Speed, Veelos, Wire
