Heavy-Duty Drive Belt Selection — Quick Reference
Heavy-duty V-belts + wedge belts transmit power between motor + driven equipment in industrial drives — slip-free torque transmission across wide speed + load range. Selection turns on section (classical vs narrow wedge vs banded), length, and brand (Gates vs Fenner = different sizing tables).
| Belt Section | Top Width | Best For |
|---|---|---|
| Classical Z / 10 | 10 mm | Smallest classical — light loads, fractional HP |
| Classical A / 13 | 13 mm | Light + medium loads — workshop machinery |
| Classical B / 17 | 17 mm | General industrial — most common workshop section |
| Classical C / 22 | 22 mm | Heavy industrial — larger drives |
| Classical D / 32 | 32 mm | Heavy industrial — mining + heavy machinery |
| Narrow Wedge SPZ / 3V | 10 mm | ~30% more power than classical Z in same envelope |
| Narrow Wedge SPA / 5V | 13 mm | ~50% more power than classical A — high-speed compact |
| Narrow Wedge SPB / 5V | 17 mm | ~70% more power than classical B |
| Narrow Wedge SPC / 8V | 22 mm | ~80% more power than classical C — heavy industrial |
| Banded V-Belts (Joined / Multi-Section) | Per section | Shock-load + high-vibration drives — anti-whip + balanced |
| Gates Predator (Aramid-Reinforced) | Per section | Mining + crushing + extreme shock — Kevlar tensile cord |
Critical: Match section to pulley section — NEVER fit SPA narrow belt to classical A pulley. Belt length per ISO 4184 nominal pitch length. Multi-belt drives = ALL belts replaced together (mismatched belt sets = uneven load). Brands: Gates, Fenner. Companion: all belts, V-belts, Predator belts, V-belt size chart.
Heavy Duty Drive Belts — Industrial V-Belts & Wedge Belts
V-belts and wedge belts are the most widely used power transmission drive in industrial equipment — providing reliable, slip-free torque transmission between motor and driven machine over a wide range of speeds and loads. AIMS Industrial stocks drive belts from Gates, and Fenner — classical A/B/C/D sections, narrow SPZ/SPA/SPB/SPC wedge belts, and banded configurations for industrial drives of all sizes.
Drive Belts We Stock
- Classical V-Belts (A, B, C, D Section): Classical V-belts to ISO 4184 standard — A (13mm top width), B (17mm), C (22mm), D (32mm). Gates Hi-Power II classical V-belts for industrial fans, compressors, agricultural drives, and general equipment replacement.
- Narrow Wedge Belts (SPZ/SPA/SPB/SPC): Narrow (wedge) V-belts provide higher power transmission in a narrower profile than classical belts — allowing more belts per drive or smaller pulleys for the same power.
- Banded (Joined) V-Belts: Banded V-belts tie multiple belt ribs together in a single assembly — preventing belt turnover and whipping on pulsating or long-centre-distance drives. Standard for large compressors, jaw crushers, and drives subject to vibration or power surges.
- Raw Edge (Cogged) V-Belts: Raw edge cogged V-belts have a cut (cog) bottom surface that reduces bending resistance on small-diameter pulleys — providing higher efficiency and longer belt life than standard wrapped belts on the same drive geometry.
V-Belt Selection & Maintenance Guide
- Belt Cross-Section Selection: Narrow (SPZ/SPA/SPB/SPC) belts transmit more power per belt width than classical (A/B/C) — use narrow belts for new designs or when upgrading existing drives. Classical belts are the correct replacement for existing classical-sheave drives.
- Replace in Sets: When replacing V-belts on a multi-belt drive, replace all belts simultaneously — mixing old and new belts distributes load unevenly, overloading the new belts and shortening the service life of the set.
- Belt Tension is Critical: Under-tensioned V-belts slip, overheat, and wear prematurely. Over-tensioned belts overload bearings and stretch cord prematurely. Gates provides tension gauges and specification tables for correct installation tension by belt section and drive centre distance.
