Twist Link Belts or Adjustable Belts

Twist 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).

Description

Twist link belts follow standard V-belt profiles and are available in common section sizes:

Belt Section Equivalent Classical V-Belt 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
