Our HTD Taper Bore Timing Pulleys are engineered for high-precision power transmission, combining the efficiency of the High Torque Drive (HTD) profile with the versatility of a taper lock bore system. Designed to eliminate slippage and reduce maintenance, these pulleys ensure synchronous motion and superior torque transfer in demanding industrial applications.
Available in a comprehensive range of pitches—including HTD 3M, 5M, 8M, 14M, and 20M—our pulleys provide a flexible solution for various load requirements. The integrated taper bore design allows for rapid installation and precise axial positioning, significantly reducing downtime during assembly or component replacement.

| System Downtime | Significant | Minimal |
The primary difference is the pitch distance between teeth. HTD 5M has a 5mm pitch, suitable for light to medium loads, while HTD 8M has an 8mm pitch, designed for higher torque transmission and heavier industrial loads.
Taper bore pulleys use a locking bushing that allows them to be mounted on various shaft sizes without the need for expensive precision boring or keyway machining, significantly speeding up installation.
For high-temperature applications, we recommend steel or cast iron pulleys, as they offer better thermal stability and structural integrity compared to aluminum.
Yes, the curvilinear tooth profile of HTD pulleys is specifically designed to reduce stress and noise, making them highly efficient for high-speed, synchronous power transmission.
Using our taper lock system allows for fine axial adjustments. We recommend using a laser alignment tool to ensure the pulley faces are perfectly parallel to prevent premature belt wear.
Yes, we offer custom manufacturing for specific tooth counts and diameters to help you achieve the exact gear ratio required for your transmission system.
