612-3M-9 HTD Timing Belt

The 3M Series HTD (High Torque Drive) Timing Belt is designed for precision, power, and efficiency in compact synchronous drive systems. With a specially engineered curvilinear tooth profile, the 3M belt minimizes stress concentration and maximizes load-carrying capacity, making it ideal for small machinery and devices that demand quiet, slip-free power transmission.

Specifications:

• Tooth Pitch: 3 mm

• Tooth Profile: Curvilinear HTD design

• Material: Durable neoprene rubber body with fiberglass tensile cords

• Tooth Face: Nylon fabric facing for reduced friction and wear

• Operating Temperature Range: -30°C to +100°C

• Available Widths: Commonly offered in 6 mm, 9 mm, and 15 mm

• Resistance: Excellent resistance to oil, heat, ozone, and abrasion

• Precision: High dimensional stability and minimal stretch for accurate timing

The 3M HTD belt is optimized for low to moderate torque loads in high-speed applications, offering efficient and quiet operation. The curvilinear tooth geometry allows for smoother meshing with pulley grooves, reducing noise and enhancing belt life.

Applications:

The 3M HTD Series is widely used in compact, high-speed mechanical systems, including:

• Office equipment (printers, copiers, scanners)

• Medical devices and diagnostic machines

• Small robotics and automation systems

• 3D printers and CNC machines

• Precision instrumentation and test equipment

• Home appliances and electric tools

Its ability to deliver accurate, synchronous movement in tight spaces makes the 3M HTD belt a reliable choice for designers and engineers. When consistent timing and torque are essential in a compact form factor, the 3M Series HTD High Torque Drive Belt offers the perfect balance of performance, longevity, and efficiency.
