ZHaonan 12T HTD5M Timing Pulley – 5-10mm Bore for 15/20mm Belts

Description

Product Overview

The ZHaonan 12-tooth HTD5M timing pulley is engineered for high‑precision power transmission in demanding industrial and scientific applications. Constructed from premium‑grade aluminum, the pulley combines lightweight characteristics with exceptional rigidity, ensuring consistent torque delivery without deformation. The short‑pitch HTD5M profile reduces backlash and enhances positional accuracy, which is critical for 3D printing, CNC machining, and other precision‑driven processes.

Key specifications include a 17.96 mm outer diameter, a selectable bore ranging from 5 mm to 10 mm, and compatibility with 15 mm or 20 mm wide HTD5M timing belts. The pulley’s 12‑tooth configuration delivers a balanced compromise between speed and torque, making it suitable for a wide range of motor speeds. Its compact design occupies minimal space on the drive shaft while providing a robust connection point for the belt.

Usage

Designed for versatility, this timing pulley integrates seamlessly into a variety of equipment. In additive manufacturing, the pulley’s precise tooth engagement minimizes layer shifting, resulting in higher‑quality prints. For CNC routers, the accurate synchronization between spindle and feed axes reduces tool wear and improves surface finish. The pulley also performs well in robotic arms, conveyor systems, and automated assembly lines where reliable timing is essential.

Installation is straightforward: select the appropriate bore size to match the motor shaft, align the pulley with the belt direction, and secure it with the supplied set‑screw. The aluminum surface is anodized to resist corrosion and wear, extending service life even in harsh environments. Users can confidently employ the pulley in both indoor workshops and outdoor field equipment.

FAQ

What belt widths are compatible with this pulley?

The pulley is designed for HTD5M timing belts that are either 15 mm or 20 mm wide. Selecting the correct belt width ensures optimal tooth engagement and power transmission efficiency.

Can I use this pulley with a motor shaft larger than 10 mm?

The available bore sizes range from 5 mm to 10 mm. For shafts larger than 10 mm, a custom adapter or a different pulley model with a larger bore would be required.

Is the aluminum surface treated for durability?

Yes, the pulley’s aluminum body is anodized, providing resistance to corrosion, wear, and surface oxidation, which extends the component’s service life in demanding environments.

How do I ensure proper alignment during installation?

Align the pulley’s teeth with the belt’s direction of travel, then tighten the set‑screw evenly. Verify that the belt runs smoothly without lateral movement before full operation.

What is the weight of the pulley and does it affect motor performance?

The pulley weighs approximately 1.1 pounds (0.5 kg). Its lightweight nature minimizes additional inertia on the motor shaft, preserving acceleration and deceleration characteristics while still providing the necessary rigidity for precise timing.

In summary, the ZHaonan 12‑tooth HTD5M timing pulley offers a blend of material quality, design precision, and versatile sizing that meets the exacting demands of modern manufacturing and automation. Whether you are upgrading an existing system or building a new machine, this pulley provides the reliability and performance needed to achieve consistent, high‑quality results.
