Texas Belting stocks 650+ industrial timing belts in every major tooth profile, pitch, width, and material from Gates, Continental (ContiTech), Bando, Megadyne, and Diesel Belting. Timing belts (also called synchronous belts) use toothed engagement with matching pulleys for no-slip, maintenance-free power transmission with exact speed ratios. They are the standard drive choice for packaging equipment, conveyors, CNC machines, servo drives, printing equipment, pumps, compressors, and any application where precise, synchronized motion is required.
Same-day shipping on stocked sizes from our Houston warehouse. We cross-reference part numbers across all manufacturers and provide expert selection assistance for any timing belt application.
Shop Timing Belts by Tooth Profile
Timing belts are organized by tooth profile family. Each profile uses a specific tooth shape that must match the pulley. Not sure which profile you have? See our Tooth Profiles Explained guide or Pitch Chart.

Frequently Asked Questions
An industrial timing belt (also called a synchronous belt) is a toothed power transmission belt that meshes with matching grooves on a toothed pulley. The teeth provide positive engagement with no slip, maintaining exact speed ratios between the driver and driven shafts. Industrial timing belts are used for conveyors, packaging equipment, CNC machines, servo drives, pumps, compressors, and any application requiring synchronized, maintenance-free power transmission.
We carry all major industrial timing belt profiles: HTD curvilinear (3M, 5M, 8M, 14M, 20M), GT/GT2/GT3 curvilinear, imperial trapezoidal (MXL, XL, L, H, XH, XXH), metric trapezoidal (T2.5, T5, T10), and advanced trapezoidal (AT5, AT10, AT20). See our Tooth Profiles Explained page for a full breakdown of each profile family.
Pitch selection depends on your drive's torque and speed requirements. Smaller pitches (3M, XL) are for light loads and small pulleys. Medium pitches (5M, L) handle general industrial drives. Larger pitches (8M, H, 14M) are for heavy duty, high-torque applications. See our Timing Belt Selection Guide for a step-by-step selection process and our Pitch Chart for a complete reference.
Both are curvilinear profiles with rounded teeth. HTD (High Torque Drive) is the standard curvilinear design. GT (Gates Tooth) is an optimized version providing near-zero backlash, up to 25% higher load capacity, and lower noise. GT3 is the current generation, using HNBR rubber for wider temperature range. See our GT Timing Belts page and Tooth Profiles Explained guide for the full comparison.
Yes. We carry FDA-approved polyurethane timing belts for direct food contact applications, plus Poly Chain GT Carbon belts that eliminate chain lubrication contamination in food processing zones. Detectable timing belts are also available for HACCP-compliant facilities. See our Food Grade Timing Belts page for compliance details.
Yes. We cross-reference part numbers across Gates, Continental (ContiTech), Bando, Megadyne, Diesel Belting, D&D Global, and OEM-specific numbers. Send us your existing part number by phone at 888-203-2358 or through our contact form and we will confirm the correct replacement from any brand.
Texas Belting stocks 650+ timing belt SKUs in Houston for same-day shipping. Standard sizes in popular profiles (HTD 5M, 8M, XL, L, H, GT3) are almost always in stock. Specialty sizes, urethane, food grade, and open-end belts typically ship within 3 to 5 business days.
Timing belts use teeth for positive, no-slip power transmission with exact speed ratios. V-belts use friction and allow 2% to 5% slip. Timing belts are preferred for precise motion control, synchronized drives, and low-maintenance applications. V-belts are simpler and less expensive for general fans, pumps, and blowers. See our full Timing Belt vs V-Belt comparison page.
