Power Transmission V-Belt

The Dayton 13G891 is a banded V-belt designed for power transmission in machinery and machine shop applications. It features a rubber compound construction with wrapped edges and polyester reinforcing cords for durability. Two bands operate together to distribute load evenly across the drive system. The belt carries industry number 2/B66 and trade size B.

Check Drive Dimensions

Verify that your equipment requires a belt with a 69.8 in outside length and a top width of 1 21/64 in before ordering. Confirm the pulley groove profile matches the B trade size and that the centre distance suits this fixed length. Ensure the operating environment stays within the -22 Degrees F to 194 Degrees F temperature range. The wrapped edge construction suits standard V-groove sheaves.

Heat and Oil Resistance

The rubber compound resists heat and oil exposure, extending service life in industrial environments where contamination or high ambient temperatures occur. Polyester cords maintain tension stability under load without stretching excessively. The banded design prevents belt whip and turnover on vertical or long-centre drives. No additional accessories or software are included with this component.

Questions about this item

Does the Dayton 13G891 2/B66 banded V-belt come as a single unit or do I need to order a matching second belt separately?

The belt is a single banded unit with two integrated ribs, so no additional belt is required for a two-groove drive.

Should I choose this 2/B66 size or a different industry number for my application?

Select this belt only when your drive calls for industry number 2/B66 with 69.8 in outside length and 1 21/64 in top width.

What does the 69.8 in outside length mean once the belt is tensioned on the pulleys?

It is the measured circumference around the outer surface; the effective pitch length on the pulleys will be slightly shorter depending on groove depth.
