The 3/BX51 Banded V-Belt is a heavy-duty 3-rib BX-series cogged PowerBand designed for higher horsepower drives where added stability and load sharing are critical. The banded construction keeps all three ribs aligned, reducing belt whip, twisting, and uneven wear under shock loads and high vibration.

Compared to 2-rib banded belts or multiple single belts, a 3/BX belt provides greater power capacity and longer service life, making it ideal for demanding industrial and agricultural equipment with frequent starts, stops, or long center distances.

This belt is commonly used anywhere a 3/BX51 banded belt is specified, including:

• 3-groove banded BX drive systems
• Equipment requiring higher horsepower capacity than 2-rib banded belts
• Drives where single belts or lighter banded belts experience slippage or premature wear

✅ Tip: Always match by belt code (3/BX51) or confirm using the inside/outside length listed in the specifications.

Profile: BX (cogged industrial V-belt)

• Heavy-duty power transmission for demanding applications
• Long-lasting, heat- and wear-resistant construction
• Low stretch for consistent performance
• Cooler, more efficient operation
• Reduced vibration and maintenance

To confirm fit:

1 Match the existing belt code (3/BX51)
2 Confirm the BX profile
3 Verify the drive requires 3-rib banded construction
4 Check inside and outside belt lengths

Q1: When should I use a 3/BX belt instead of a 2/BX belt? Use a 3/BX banded belt when the drive requires higher horsepower capacity, improved load sharing, or when 2-rib belts wear out or slip too quickly.

Q2: Can a 3/BX belt replace three single BX belts? Yes. Banded belts are designed to keep ribs aligned, reducing twisting and uneven tension compared to running single belts.

Q3: What does “3/BX51” mean? “3/” indicates three ribs (banded), “BX” is the belt profile, and “51” refers to the belt length designation.

Q4: What’s the difference between BX and B belts? BX belts are cogged/notched, allowing better flexibility, cooler operation, and improved performance over classic B-section belts.

Q5: Why do high-horsepower belts fail early? Common causes include pulley misalignment, incorrect belt sizing, worn sheaves, or insufficient rib count for the horsepower load.

Q6: How fast do you ship? Orders placed before 3pm CST ship same-day.
