Why Belt Part Numbers Are the Same Across Brands

Unlike bearings (where SKF uses “2RS1” and NSK uses “DDU” for the same seal type), V-belt manufacturers all use the same industry-standard naming system. An A68 from Gates is the same dimensions as an A68 from Continental, Optibelt, Dayco, or Bando.

The letter designates the cross-section profile (A, B, C for classical; 3V, 5V for narrow) and the number designates the length. This standardization is based on RMA/MPTA and ISO standards that all manufacturers follow.

The differences between brands are in rubber compound, cord construction, and manufacturing quality — which affect belt life and performance under extreme conditions. For standard applications, all brands are fully interchangeable.

Frequently Asked Questions

Can I replace a Bando B106 with a Continental B106?

Both are listed against the same base belt specification and the same standard designation, so they share dimensions. Confirm construction type and rating for demanding applications.

Which brand of B106 belt is best?

We list 5 brands for this belt: Bando, Continental, Dayco, Gates and Optibelt. They share dimensions; brands differ in rubber compound and cord construction, which affect life under heat, shock load, and misalignment rather than fit.

What's the difference between B106 and BX106?

The “X” suffix (e.g., AX68 vs A68) indicates a notched/cogged construction. Notched belts run cooler and are more flexible, allowing use on smaller pulleys. Same length and width — different internal construction.
