The Optibelt A 79 is a classical V-belt in the VB / Red Power series with an A profile and a 2057 mm length. Before fitting it, inspect the drive and sheaves so the new belt runs true and wears evenly.
Check sheave grooves for wear, rust, or embedded debris that can cut the belt. Confirm the grooves match the A profile: 13 mm top width, 8 mm height, and 40° angle. Misaligned or worn sheaves will shorten belt life no matter how good the belt is.
Verify alignment with a straightedge across both sheaves, and check that the motor and driven equipment are securely mounted. Tension the belt according to your drive manufacturer's procedure, then recheck after the first run-in period. The same size is also listed under Stark A 79 if you are comparing markings.

Frequently asked questions
- What should I check on the drive before installing this belt?
- Inspect sheave grooves for wear, rust, or debris, confirm the A profile dimensions (13 mm top width, 8 mm height, 40° angle), and check alignment with a straightedge. Also verify that all mounting bolts are tight.
- How do I confirm this is the right belt for my drive?
- Read the marking on the old belt. You need an A profile and a 2057 mm length. If the old belt is unreadable, measure the top width and height, and the outside length, then compare to 13 mm, 8 mm, and 2057 mm.
- What information should I send for a quote?
- Send the part number A 79 and the brand Optibelt, along with the quantity you need. If you are replacing a different brand, include the old belt's marking so we can help confirm the match.
