Industrial Banded V-Belt for Heavy-Duty Drives

The Dayton 3/B112 banded V-belt uses three B-section bands joined into a single 115.8 inch closed loop. Gum rubber construction with polyester reinforcing cords handles general industrial power transmission where matched single belts might roll or jump off pulleys.

Suits Multi-Groove Sheaves Up to 194 Degrees F

This belt fits drives that accept a 2 inch top width and 0.5 inch thickness on sheaves with at least a 5.4 inch pitch diameter. Operations needing a different band count, longer or shorter length, or temperature resistance beyond the -22 to 194 degree F range should select another size.

Simple Drop-In Replacement on Aligned Sheaves

Installation follows standard V-belt procedure: relieve tension, remove the old banded belt, seat the new unit in all three grooves, then retension to specification. Misaligned pulleys or worn groove profiles are the most common cause of premature edge wear or band separation.

Questions about this item

What minimum pulley pitch diameter is required for this 3/B112 banded V-belt?

The belt requires a minimum pulley pitch diameter of 5.4 in to operate correctly.

Can this banded V-belt replace individual B-section belts on my existing drive?

Yes, the 3-band design matches the B trade size and 115.8 in outside length, replacing three separate B-section belts on the same pulleys.

How do I confirm the belt is tensioned properly after installation?

After installation, the belt should run smoothly without slip or squeal at startup, and the top width of 2 in should sit evenly across all three bands in the pulley grooves.
