The 2/AX78 Banded V-Belt is a heavy-duty 2-rib AX-series cogged PowerBand belt engineered for demanding drive systems where single belts slip, twist, or wear unevenly. The banded construction keeps both ribs aligned for smoother performance, better load distribution, and improved stability under shock loads and vibration.

AX-series belts are commonly used where flexibility and strong grip are required, and the cogged design allows cooler operation and tighter bending around pulleys compared to standard wrapped belts. This makes the 2/AX78 banded belt a reliable replacement for industrial, agricultural, and compressor equipment.

✅ Fast fulfillment: Orders placed before 3pm CST ship same-day.

Air compressors and shop equipment

Agricultural machinery

Pumps and blowers

Industrial conveyors and material handling systems

Woodworking and manufacturing equipment

Multi-belt drives requiring stable alignment

This belt is commonly used anywhere a 2/AX78 banded belt is specified, including:

Dual-groove banded drive systems requiring AX profile belts

Equipment needing improved grip and stability over single belt setups

Drives where vibration causes premature wear or belt flipping

✅ Tip: Always match your belt by belt code (2/AX78) or confirm using the belt’s inside/outside length specifications.

Also searched as: AX78 banded belt, 2 rib AX78 belt, AX78 PowerBand

Profile: AX (cogged industrial V-belt profile)

Helps reduce belt whip, twisting, and roll-over

Improves belt alignment compared to running separate single belts

Better load distribution for longer belt life

Designed for demanding applications with high vibration or sudden load changes

Cogged design increases flexibility and reduces heat buildup

To ensure correct fit:

1. Match your existing belt code (2/AX78)

2. Confirm the belt profile is AX

3. Verify the system requires a 2-rib banded belt

4. Confirm length by measuring inside circumference or checking your original belt markings

Q1: What does “2/AX78” mean?
“2/” indicates two ribs (banded belt), “AX” is the belt profile, and “78” refers to the belt length designation.

Q2: Can I replace two single AX belts with one 2/AX banded belt?
Yes. A banded belt is designed to keep both ribs aligned and reduce twisting, which improves belt stability and wear life.

Q3: What is the difference between AX and A belts?
AX belts are typically cogged/notched, providing better flexibility and cooler operation compared to standard A-section belts.

Q4: Why should I use a banded belt instead of single belts?
Banded belts help reduce belt whip and uneven tension, especially in high vibration or shock-load applications.

Q5: What causes AX belts to fail early?
Common causes include pulley misalignment, worn sheaves, incorrect belt sizing, contamination (oil/dust), or using a belt that is not rated for the horsepower load.

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