Technical Specs

Materials

  • Neoprene and PU timing belts with tensile cords

Sizes

  • Pitch, width, and tooth count alignment

Standards

  • HTD, STD, AT, GT profile families

Problem this solves

Timing belts fail quickly when tooth profiles do not match the pulleys. This guide highlights the common mismatch errors.

Tooth profile pitfalls

IssueCauseImpact
Skipping teethWrong pitch or profileLost timing
Rapid wearMismatched pulley formShort belt life
NoiseIncorrect tensionPremature fatigue

Matching steps

  1. 1Confirm the pulley pitch and tooth profile.
  2. 2Match belt width and tooth count.
  3. 3Check reinforcement type for load and speed.
  4. 4Verify tensioning method and alignment.

RFQ checklist

  • Belt profile and pitch
  • Belt width and tooth count
  • Pulley profile and tooth count
  • Operating speed and load

FAQ

  • Q: Can I replace HTD with GT? A: Only if pulleys match the GT profile.
  • Q: Do you need pulley samples? A: Photos and measurements are usually enough.
  • Q: What if the belt code is missing? A: Provide pulley pitch and belt width.
