T5 Timing Belts (5mm Metric Trapezoidal)

T5 timing belts are metric trapezoidal synchronous belts with a 5mm pitch, widely used in European-manufactured equipment, linear motion systems, textile machinery, and precision automation. The T-profile (sometimes called "T-series" or "metric trapezoidal") was developed in Europe and is the standard tooth form on equipment from German, Italian, Swiss, and Scandinavian OEMs. Texas Belting stocks T5 timing belts in neoprene and urethane constructions with fiberglass, steel cord, and Kevlar tensile cord options.

T5 Is NOT the Same as 5M

This is the single most important thing to know about T5 timing belts. T5 and 5M (HTD) both have a 5mm pitch, but they use completely different tooth shapes and completely different pulleys. Mixing them causes premature wear, tooth shear, and belt failure.

T5 Timing Belt Part Number Decoder

How to calculate teeth: Divide pitch length by 5. Example: 450 / 5 = 90 teeth. Open-end T5 belts are sold by the meter or foot and cut to length, then joined with a mechanical splice or welded connection. Some manufacturers reverse the order or omit the "T5" prefix, listing it as 450-T5-16. See our Pitch Chart for all format variations.

T5 vs. AT5: What Is the Difference?

AT5 is a modified version of the T5 profile with a slightly different tooth geometry designed for higher load capacity and improved engagement. AT5 was developed to address the tooth stress concentration limitations of the standard T5 profile while maintaining compatibility with the same pitch and width dimensions.

T5 for Linear Motion and Positioning

T5 is one of the most popular profiles for linear motion applications. Open-end urethane T5 belts with steel tensile cord provide the near-zero stretch that linear actuators, gantry systems, and pick-and-place machines require for repeatable positioning.

• Open-end urethane T5 with steel cord is the standard for linear motion. Cut to any length and joined with a mechanical connector or welded splice.
• Steel cord provides 0.02% elongation under load, ensuring that the carriage position corresponds exactly to the motor shaft rotation without drift.
• T5 at 16mm or 25mm width handles most linear motion loads. For heavier gantry systems, step up to T10 (10mm pitch) or AT10.
• Urethane body resists oils, chemicals, moisture, and particulate contamination common in manufacturing environments.

Common T5 Timing Belt Applications

T5 Timing Belt Materials

Neoprene (standard): Neoprene body with fiberglass tensile cord. Standard construction for closed-loop T5 belts. Temperature range -30°F to 185°F. Available from Gates, Continental, Diesel Belting, and other manufacturers.

Urethane with steel cord: The standard for linear motion and precision applications. Near-zero stretch. Available in closed-loop and open-end (cut to length). FDA-compliant compounds available for food processing.

Urethane with Kevlar cord: For applications requiring high flex life with low stretch. Better fatigue resistance than steel cord around small pulleys.

Open-end: Urethane T5 belts are available in open-end rolls (typically sold by the meter). Cut and joined to any required length. This is the standard format for linear motion drives and custom center distance applications. Open-end neoprene T5 is not available.
