H Timing Belts – High-Performance H Series Timing Belt Range

At Bolton Engineering Products Ltd, we supply premium-quality H timing belts (1/2” pitch) designed for precision, durability, and reliability. Our H series timing belts are part of the imperial timing belt range, ideal for industrial and commercial applications requiring accurate power transmission and smooth, synchronized operation.

What Is an H Type Timing Belt?

The H type timing belt(pitch 1/2 ) has a trapezoidal tooth profile, which exactly mates with the matching tooth space of a pulley. This makes it preferred in systems for which timing accuracy and low noise performance are paramount.

Common Applications:

  • Machine tools and textile machinery
  • Food processing and packaging systems
  • Postal and sorting machines
  • HVAC and automation equipment
  • Outdoor power tools and general industrial machinery
