Question 1

Why use a Banded belt instead of individual belts?

Accepted Answer

Banded belts (or Kraftbands) are essential for drives with pulsating loads or long center distances. They prevent individual belts from whipping, twisting, or jumping out of the groove by tying them together with a high-strength tie-band, ensuring the entire drive functions as a single stable unit.

Question 2

Do I need special pulleys for banded belts?

Accepted Answer

Typically, no. SQUAREROPE Banded Belts are designed to fit standard ISO/RMA multi-groove pulleys. However, ensure your pulley grooves are evenly spaced and not excessively worn, as the tie-band requires proper alignment to prevent bottoming out.

Question 3

Can I get a banded belt in any size?

Accepted Answer

We offer Banded Belts in all standard profiles (A, B, C, 3V, 5V, 8V). While common sizes are stocked, specific rib-counts (e.g., a 5-rib 5V belt) are often made-to-order. Please verify the exact number of grooves and the effective length required.

Question 4

My banded belt is separating. Why?

Accepted Answer

Separation of the tie-band usually occurs if the belt rides too deep in the groove or if the pulley's outer diameter interferes with the band. Ensure your pulleys are compatible and that there is no debris (rocks, tools) wedged between the belt and the pulley.

Question 5

Is it just glued together?

Accepted Answer

No. SQUAREROPE Banded Belts are manufactured using a "single-shot vulcanization" process. The tie-band and the V-belts are cured together as one cohesive chemical unit, not glued. This ensures exceptional bond strength that won't delaminate under heavy shock loads.
