Single-Sided Timing Belt Selection — Quick Reference (Gates PowerGrip)
Single-sided synchronous timing belts deliver positive (slip-free) drive for conveyor + indexing + positioning + automation applications. Tooth profile + pitch determine drive precision + power capacity. Gates is the AU industrial standard.
| Belt Section | Tooth Pitch | Best For |
|---|---|---|
| Gates PowerGrip MXL (Mini) | 0.080" pitch | Precision low-power drives — instruments + small automation |
| Gates PowerGrip XL | 0.200" pitch | Office equipment + small motion control |
| Gates PowerGrip L | 0.375" pitch | Light industrial automation |
| Gates HTD 3M (Curvilinear) | 3mm pitch | Light industrial + automation — modern profile |
| Gates HTD 5M (Curvilinear) | 5mm pitch | General industrial conveyor + automation |
| Gates HTD 8M (Curvilinear) | 8mm pitch | Medium industrial — pumps + larger conveyors |
| Gates HTD 14M (Curvilinear) | 14mm pitch | Heavy industrial — high-power drives |
| Gates GT3 (Higher-Capacity) | Various — modified curvilinear | Power capacity ~30% higher than HTD same pitch |
| Gates PowerGrip H (Classical Trapezoidal) | 0.500" pitch | Older equipment + replacement on legacy drives |
HTD vs Classical: HTD (Curvilinear) tooth profile has rounded teeth that distribute stress + handle higher belt-entry loads vs classical trapezoidal. HTD is the modern standard for new design. Classical sections kept for replacement on older equipment. Critical: belt tooth pitch + pulley tooth pitch MUST match exactly — even close pitches (e.g. HTD 5M vs 3M) are NOT interchangeable. Brand: Gates. Companion: all belts, timing belts, double-sided timing belts, timing pulleys.
Single-Sided Timing Belts
AIMS Industrial stocks single-sided synchronous timing belts from Gates covering the full range of industrial and automation drive applications. From classical trapezoidal tooth belts through to advanced curvilinear profiles, we stock the sections most commonly used in Australian industrial and manufacturing operations.
Gates PowerGrip HTD Belts
HTD belts in 3M, 5M, 8M and 14M section provide accurate synchronous transmission for conveyor, indexing and positioning drives. The rounded HTD tooth profile reduces stress concentration and handles higher belt entry loads than classical trapezoidal profiles, making HTD the standard selection for most new industrial synchronous drive designs.
Gates PowerGrip GT4 & GT3 Belts
The PowerGrip GT4 (8MGT, 14MGT) and GT3 (3MGT, 5MGT, 8MGT, 14MGT) series feature an advanced curvilinear tooth geometry that delivers higher power ratings than equivalent HTD belts with lower noise and vibration. GT3 and GT4 belts are the Gates premium industrial synchronous belt range, suited to high-speed and high-torque drives where HTD performance margins are insufficient.
Classical Synchronous Belts
Gates PowerGrip classical belts in XL, L, H and XH sections serve the extensive installed base of imperial trapezoidal tooth drives in agricultural, industrial and imported equipment.
Synchro-Power Polyurethane Belts
Gates Synchro-Power PU belts in T5, T10, AT5 and AT10 sections are manufactured from polyurethane with steel cord reinforcement. Higher stiffness and resistance to oils, chemicals and wide temperature ranges make them well-suited to precision positioning and light automation drives, particularly where the environment would degrade a rubber belt.
Long Length Belts
Long length Gates HTD 8M belts in glass cord and aramid cord rubber construction are available in 30m rolls for conveyor drives, custom machinery and applications where standard belt lengths are insufficient. Custom length synchronous belts for bespoke drive configurations.
People Also Ask — Single-Sided Timing Belts
Q: What's a single-sided timing belt and where is it used?
Single-sided timing belts have teeth on one face only — the other face is smooth. They're the standard for most positive-drive applications: 3D printers, CNC motion control, conveyors with simple linear drive, automotive timing belts, and any application where the belt engages a single set of pulleys. Double-sided belts (teeth on both faces) are used in serpentine drives where the belt engages multiple pulleys on alternating sides.
Q: What profile should I choose?
Profile is determined by the belt and pulley together — they MUST match. Common profiles include HTD (3M, 5M, 8M, 14M pitch), GT and GT2 (modified curvilinear), Powergrip (HTD evolution), and trapezoidal (T, MXL, XL, L, H). Modern industrial timing applications typically specify HTD or GT; older equipment may still use trapezoidal. Identify the existing belt and pulley profile before ordering replacements.
Q: How do I measure a timing belt for replacement?
Three dimensions: belt width (face width across the teeth), tooth pitch (centre-to-centre distance between adjacent teeth), and overall length (pitch length, measured around the belt's pitch line). Combined: profile-pitch length-width gives the full spec (e.g. 8M-1280-30 = 8M profile, 1280mm pitch length, 30mm wide). Measure carefully — substituting different lengths changes the drive geometry.
Q: What materials are timing belts made from?
Neoprene rubber over fibreglass tensile cords is the workshop standard — good general-purpose performance. Polyurethane belts with steel or Kevlar cords handle higher loads and tighter tolerances — used in positioning applications. Specialty belt materials (HNBR, EPDM) for extreme temperature or chemical exposure. For most workshop replacements, neoprene-fibreglass matches the original.
Q: How tight should a timing belt be tensioned?
Tighter than V-belts but not over-tensioned — belt manufacturers publish specific tension specs for each profile and size. General guide: deflect the longest belt span about 16mm per metre of span with light hand pressure. Over-tensioning loads bearings and stretches the belt; under-tensioning lets teeth jump under load. Use a belt tension gauge for precision applications.
