Dayton 5/B128 Banded V-Belt Overview

The Dayton 13W301 is a 5-band wrapped V-belt built for heavy-duty power transmission. It uses a rubber compound with polyester reinforcing cords to handle high-torque industrial drives. The belt carries industry number 5/B128 and trade size B for direct replacement identification.

Suited for Multi-Groove Industrial Drives

This banded design suits drives requiring five matched ribs in a single belt to prevent turnover and vibration. It operates reliably between -22 and 194 degrees Fahrenheit with heat and oil resistance. Single-belt drives or applications needing a different band count or cross-section should look at alternative belt types.

Fits 131.8-Inch Outside Length Pulleys

The belt requires pulleys gapped for a 131.8-inch outside length and a 3-21/64-inch total top width across five bands. Its half-inch thickness seats deep in standard B-section grooves for secure grip. The wrapped construction protects the cords from abrasive debris in open machinery environments.

Questions about this item

What pulley groove spacing matches the 3 21/64 in top width of this 5-band belt?

Each band follows the standard B-section groove profile, so a matched 5-groove sheave set with B-dimension spacing will align with the 3 21/64 in overall width.

Can this banded belt replace five separate B128 belts on an existing drive?

Yes, the 5/B128 designation means it directly substitutes five individual B128 belts on the same sheaves, keeping the 131.8 in outside length and 1/2 in thickness unchanged.

How can I confirm the belt is tensioned correctly after installation?

Measure the deflection force at mid-span; the polyester cords should allow the specified deflection per inch of span without exceeding the 194 Degrees F operating limit during run-in.
