Why HTD Timing Belts: 5M 8M 14M Synchronous Belts
HTD timing belts (5M, 8M, 14M) for power transmission and linear drives. Open-ended and endless options, fiberglass and steel tension members.
- Precision Single-Sided, Double-Sided & Open-Ended Options HTD belts are available as single-sided (teeth on one face), double-sided (teeth on both faces, for serpentine or reverse-bend drives), and open-ended (cut to length for linear motion systems). Open-ended HTD 5M and 8M belts are common in linear actuators, gantry systems, and 3D printer and CNC axes.
- Built for Accurate, Slip-Free Operation The positive engagement between belt teeth and pulley grooves means output speed stays locked to input speed — no slip, no tension loss over time. For positioning systems that need repeatable accuracy, this is the difference between a drive and a guess.
- Reinforced for Strength & Longevity Tension members run the full belt length and carry the load:
- Wide Tooth Profile Compatibility HTD belts pair with HTD pulleys in the standard pitches:

FAQ
Questions Buyers Ask
What is an HTD timing belt?
An HTD (High Torque Drive) timing belt is a synchronous belt with a curvilinear tooth profile. The rounded teeth engage progressively with pulley grooves, which allows higher torque transmission and quieter operation than trapezoidal-tooth belts.
What is the difference between HTD 5M, 8M, and 14M?
The number is the tooth pitch in millimeters. HTD 5M has a 5 mm pitch and is used in light to medium drives (linear actuators, small conveyors); HTD 8M (8 mm pitch) covers general power transmission; HTD 14M (14 mm pitch) is for heavy industrial drives.
Can you cut HTD timing belts to custom widths and lengths?
Yes. Open-ended HTD belts are cut to the exact length you need and slit to custom widths. Endless (joined) belts are made to order in standard and non-standard lengths.
What tension member should I choose?
Fiberglass cord for standard drives, aramid for shock loads and high-speed applications, steel for maximum stiffness in precision linear drives. The tension member carries the working load — the teeth only position it.
How do HTD belts compare to trapezoidal (T/AT) belts?
HTD's curvilinear tooth distributes load over a larger area, so it can carry more torque at the same width and tends to run quieter. Trapezoidal belts (T5, T10, AT5, AT10) are still common where the drive was originally designed around them.
