Industrial Timing Belts

Industrial Timing Belts — HTD, GT & Synchronous Drive Belts

Industrial timing belts provide synchronous power transmission — maintaining an exact speed ratio between drive and driven sprockets with no slip. AIMS Industrial sells timing belts from Gates, the world’s leader in belt technology — HTD (High Torque Drive), GT2/GT3 (Gates Tooth), T-series, and XL/L/H synchronous belts for industrial machinery, CNC equipment, and precision drive applications.

Timing Belts We Stock

• HTD Timing Belts (3M, 5M, 8M, 14M): HTD (High Torque Drive) timing belts with rounded tooth profile in 3mm, 5mm, 8mm, and 14mm pitch — the dominant industrial synchronous belt standard for machine tools, conveyor drives, and power transmission applications requiring high torque density and long belt life.
• GT2/GT3 Timing Belts: Gates PowerGrip GT2 and GT3 timing belts with modified curvilinear tooth profile — providing higher tensile strength, reduced backlash, and improved tooth engagement compared to standard HTD. GT3 provides higher power density than GT2 in the same pitch and width.
• T-Series Timing Belts (T5, T10, T20): T-series timing belts with trapezoidal tooth profile in 5mm, 10mm, and 20mm pitch — the European DIN standard for industrial synchronous drives.
• Classical Synchronous (XL, L, H, XH): Classical synchronous belts in inch pitch (XL = 1/5", L = 3/8", H = 1/2", XH = 7/8") for older American-designed machinery and existing drives using classical timing belt standards.

Timing Belt Selection & Maintenance Guide

• Pitch and Width Selection: Timing belt selection requires matching pitch to the existing pulley/sprocket, confirming belt width to the drive power requirement, and selecting belt length. Gates provides design software and selection tables for new and replacement belt design.
• Belt Tension — Not a V-Belt: Timing belts operate at much lower tension than V-belts — excessive tension dramatically reduces bearing and belt life. Install to the manufacturer's specified strand tension using a frequency meter or tension gauge, not by deflection feel.
• Replacement Interval: Timing belts should be replaced on a scheduled interval (typically 2–4 years or per machine manufacturer specification) rather than run to failure — a timing belt failure in a CNC, indexing, or synchronous drive can cause significant secondary machine damage.
