Fenner Precision manufactures standard Fenatrak® multi-v belts from polyurethane elastomers reinforced with Kevlar® and in the three pitches SG®H, H & J section.
Fenatrak multi-v urethane belts are ideal for use in non synchronized applications. They are quiet, smooth running and are an effective solution for drives where high speed, high torque, and shock loads are design factors.
SG®H is the preferred tooth profile because it provides the most torque transmission and flexes around smaller pulleys. This shortened v-rib profile provides long life and increased flexibility for high ratio and high speed drive applications where small pulleys are used. Our manufacturing process insures accurate molding tolerances that exceed RMA specifications. Each rib is designed to fit precisely into the drive pulley, delivering a smooth, quiet transmission.

Standard Multi-V Belt Specifications
- The standard urethane hardness is 80 Shore A durometer. Other durometers are available – 60 Shore A to 95 Shore A. Polyurethane backings provide abrasion resistance and accurate molding tolerances.
- The standard reinforcement is KEVLAR® which provides excellent strength and high modulus. Depending on your need, Fenner Precision can provide other aramids along with polyester and fiberglass for applications with special requirements.
- The standard operating temperature range is -40’C (104’F to 80’C (176’F)
- The standard surface impression is textured; however, smooth surfaces are available on request for some conveying applications.
