Belts, Twisted Link Adjustable V-Belt, V-BeltsTwist Link Belts or Adjustable Belts
Twist link belts, also known as adjustable V-belts, are a modular alternative to traditional rubber V-belts, designed to be easily adjusted in length without requiring special tools. They are made from interlocking polyurethane/polyester links, allowing users to customize belt length on-site and replace damaged sections without dismantling the entire drive system. They have a modular link construction with individual belt segments (links) that are connected together, forming a flexible, high-strength belt. There is no Need for Pre-Measured Lengths as the belt can be cut to any length and reassembled. Most importantly they have a universal fit meaning that they can be used in any standard V-belt pulley (A, B, C, Z sections).
Twist link belts follow standard V-belt profiles and are available in common section sizes:

Common Applications |
| Z/10 |
10 mm (3/8″) |
Light-duty drives, small motors |
| A/13 |
13 mm (1/2″) |
General industrial, HVAC, pumps |
| B/17 |
17 mm (5/8″) |
Heavy-duty machinery, compressors |
| C/22 |
22 mm (7/8″) |
Large industrial fans, crushers |
Understanding the Nomenclature
- The belt is designated by its section (Z, A, B, C, D), and its length is determined by the number of links used.
- Example: A/13 section belt cut to 1200 mm means:
- A section
- 1200 mm total assembled length
