  • Four bands share load evenly for smoother power transfer
  • Wrapped gum-rubber construction resists abrasion and oil in general industrial use
  • Polyester reinforcing cords maintain tension and reduce stretch over time
  • 8 in outside length fits drives requiring a 4/B136 industry number
  • Operates up to 194 °F on pulleys as small as 5.4 in pitch diameter

Industrial Power Transmission Belt

The Dayton 3HFA5 4/B136 is a banded V-belt built for general industrial drives. Four joined strands share the load evenly across the pulley, reducing whip and vibration in demanding machinery setups. Gum rubber construction with polyester reinforcing cords resists stretch and heat up to 194 degrees Fahrenheit. The closed-loop design measures 139.8 inches outside length and 2 43/64 inches top width.

Suited for Multi-Groove Drives.

This belt fits drives that require a B-series banded profile with four ribs and a minimum pulley pitch diameter of 5.4 inches. It serves conveyors, fans and heavy equipment where matched-set tension matters. Operations needing a single V-belt, a different trade size or a shorter outside length should select an alternative product.

Wrapped Edge and Rubber Coating Extend Service Life

The wrapped edge construction protects the reinforcing cords from abrasion and contamination. A rubber coating adds oil and ozone resistance for harsh plant environments. Together these features maintain consistent grip and reduce replacement frequency on Power King Combo series drives. No additional hardware or lubrication is included.

Questions about this item

Does my drive need a 5.4 in minimum pulley pitch diameter for this 4/B136 banded belt?

Yes, the belt is rated for a minimum pulley pitch diameter of 5.4 in, so your drive pulleys must meet or exceed that size for proper operation.

Can I pair this 139.8 in outside-length banded belt with an existing single B-section belt on the same drive?

No, this banded belt contains four joined strands and must run on a matching multi-groove sheave; mixing it with a single belt would cause uneven load sharing and premature wear.

How do I confirm the 2 43/64 in top width is seated correctly after installation?

Check that each band sits flush in its groove with no visible gap, verify the 139.8 in outside length matches the drive centres, and run the drive briefly to ensure smooth, quiet operation without vibration.
