Why Megadyne for HVAC Drives?

Megadyne belts deliver stable traction, reduced slip, and lower heat build-up—key to quieter operation and longer bearing life. Choose classic wrapped V-belts for durability, cogged V-belts for higher efficiency on small pulleys, poly-V for compact multi-rib drives, and synchronous for positive, no-slip transmission.

Sheaves, Bushings & Setup Tools

Match belts with V-belt sheaves and taper-lock / QD bushings. Speed installs and reduce wear using a belt tension gauge, laser pulley alignment tool, and pulley puller.

How to Identify the Correct Belt

  1. Read the belt part code (e.g., AX40, B72, 4L450, 1500-8M) if present.
  2. If missing, measure top width and effective length; note pulley section (A/B/3L/4L/5L, PK ribs, or HTD pitch).
  3. Search here: Megadyne belt or send your dimensions—our team will cross-reference equivalents.
