Belts that keep HVAC blowers and fan drives running
Megadyne® power transmission belts are designed for dependable performance in HVAC drive applications—especially on blower assemblies, belt-driven fans, and motor/pulley systems. A properly matched belt helps maintain airflow performance, reduces squeal and slip, and supports long motor and bearing life.
When replacing a belt, it’s important to confirm the belt profile and the correct length for your pulley spacing. If the belt is too loose, it can slip and wear prematurely. If it’s too tight, it can overload bearings and shorten component life.
If you want a fast match, send the belt numbers from the old belt (if readable) or share the drive setup and measurements and we’ll help you identify the right Megadyne option.

Megadyne HVAC Belts — FAQs
How do I identify the correct replacement belt?
The fastest method is using the belt number printed on the old belt. If it’s worn off, measure the approximate length and confirm the belt profile (V-belt or ribbed).
What happens if belt tension is incorrect?
Too loose can cause slip and noise; too tight can overload bearings and shorten motor life. Proper tension improves airflow consistency and belt life.
Should I keep spare belts on hand?
Yes—common belt sizes are worth stocking for quick service turnarounds, especially on commercial blower and fan equipment.
