Diesel Belting Timing Belts

Q: What timing belt profiles does Texas Belting carry?

Texas Belting carries all major 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).

Q: How do I choose the right timing belt pitch?

Pitch selection depends on torque and speed. Smaller pitches (3M, XL) for light loads, medium pitches (5M, L) for general industrial, larger pitches (8M, H, 14M) for heavy duty. Texas Belting provides a complete Timing Belt Selection Guide and Pitch Chart for reference.

Q: What is the difference between HTD and GT timing belts?

Both are curvilinear with rounded teeth. HTD is the standard design. GT is optimized for near-zero backlash, up to 25% higher load capacity, and lower noise. GT3 is the current generation using HNBR rubber for wider temperature range.

Q: Do you stock food grade timing belts?

Yes. Texas Belting carries FDA-approved polyurethane timing belts for direct food contact, Poly Chain GT Carbon for lubrication-free food zones, and detectable timing belts for HACCP-compliant facilities.

Q: Can you cross-reference timing belt part numbers?

Yes. Texas Belting cross-references part numbers across Gates, Continental, ContiTech, Bando, Megadyne, Diesel Belting, D&D Global, and OEM-specific numbers. Call 888-203-2358 or submit through the contact form.

Q: What is the lead time for timing belts?

650+ SKUs are stocked in Houston for same-day shipping. Standard sizes in popular profiles are almost always in stock. Specialty, urethane, food grade, and open-end belts typically ship within 3 to 5 business days.

Q: What is the difference between a timing belt and a V-belt?

Timing belts use teeth for positive, no-slip drive with exact speed ratios. V-belts use friction and allow 2% to 5% slip. Timing belts are preferred for precision and low maintenance. V-belts are simpler for general fans, pumps, and blowers.

Frequently Asked Questions

What is an industrial timing belt?▼

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.

What timing belt profiles does Texas Belting carry?▼

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.

How do I choose the right timing belt pitch?▼

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.

What is the difference between HTD and GT timing belts?▼

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.

Do you stock food grade timing belts?▼

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.

Can you cross-reference timing belt part numbers?▼

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.

What is the lead time for timing belts?▼

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.

What is the difference between a timing belt and a V-belt?▼

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.
