HTD 3M Timing Belts – Precision Synchronous Belts for Compact Drives

At Bolton Engineering Products Ltd, we supply a complete range of HTD 3M timing belts, engineered for accurate, smooth, and reliable motion transfer in light- to medium-duty applications.

Our HTD belts use a curvilinear tooth profile that offers higher load capacity and reduced slippage compared to standard trapezoidal belts.

Whether you need a replacement 3M timing belt or are designing a compact synchronous drive system with an HTD 3M synchronous timing pulley, BEP Ltd provides premium belts for high-precision performance.

What Are HTD 3M Timing Belts?

The HTD 3M belt is a synchronous drive belt with a 3mm pitch between each tooth.
It works in combination with matching HTD 3M synchronous timing pulleys to deliver:

  • Smooth torque transmission
  • Zero slippage
  • Quiet operation
  • Precise speed ratio control
  • These belts are ideal for compact mechanical systems requiring accuracy and reliability.

Common Applications Include:

  • 3D printers and small CNC machines
  • Robotics and automation equipment
  • Office machinery
  • Packaging and light conveyor systems
  • Electronic assembly tools

FAQs

Q1: What does HTD 3M mean?

“HTD 3M” refers to a High Torque Drive belt with a 3mm pitch tooth spacing and a rounder, curvilinear tooth design for improved torque transmission.

Q2: Are HTD belts interchangeable with trapezoidal timing belts?

No. HTD belts require matching HTD pulleys due to their unique tooth shape.

Q3: What width should I choose — 6mm, 9mm, or 15mm?

  • 6mm for very light-duty applications
  • 9mm for standard compact drives
  • 15mm for higher torque loads

Q4: Do you supply pulleys for HTD 3M timing belts?

Yes, we also stock HTD 3M synchronous timing pulleys compatible with every 3M belt profile.
