Timing Belt Pulley 6.35mm Aluminum Bore for 3D Printer CNC by JiuWu

Description

Product Overview

The JiuWu timing belt pulley set is engineered for precision and durability, offering a 12‑tooth profile that meshes perfectly with standard GT2 timing belts. Each pulley is machined from aerospace‑grade aluminum, providing a lightweight yet robust component that resists corrosion and wear over prolonged use. The 6.35 mm bore is sized to accept common 6.35 mm (¼‑inch) shafts, making installation straightforward on a wide range of 3D printer and CNC machine frames. The set includes two identical pulleys, allowing users to create a complete drive system with consistent tension and reduced backlash.

Key specifications include a 12‑tooth count, a 6.35 mm bore, and a compact outer diameter of 12 mm, which fits within tight mechanical envelopes. The pulleys are finished with a smooth, anodized coating that enhances surface hardness and provides a sleek, professional appearance. With a package weight of just 1.59 oz, the pulleys add minimal mass to moving assemblies, preserving the dynamic performance of high‑speed motion systems.

Usage

Designed for both hobbyist and industrial environments, these pulleys excel in applications where precise linear motion is critical. In 3D printers, the pulleys drive the X, Y, and Z axes, ensuring accurate layer placement and smooth filament extrusion. CNC machines benefit from the same reliability, using the pulleys to power spindle movement, tool changers, and axis drives with minimal vibration. The lightweight aluminum construction reduces inertia, allowing faster acceleration and deceleration without sacrificing positional accuracy.

Beyond printers and CNCs, the pulleys are suitable for any system that employs GT2 timing belts, such as robotic arms, conveyor belts, and automated camera sliders. Their universal 6.35 mm bore accommodates standard motor shafts, making them a versatile upgrade for existing equipment or a foundational component for new builds. Users can expect quieter operation, lower heat generation, and extended belt life due to the precise tooth geometry and high‑quality material.

FAQ

What size motor shaft can these pulleys accommodate?

The pulleys feature a 6.35 mm (¼‑inch) bore, which is compatible with most stepper and DC motor shafts used in 3D printers and CNC machines. If your motor has a different shaft diameter, a simple adapter or sleeve can be used to achieve a secure fit.

Are these pulleys compatible with GT2 timing belts?

Yes, the 12‑tooth design is specifically intended for GT2 timing belts, providing a 2 mm pitch that matches the standard belt specifications. This ensures optimal tooth engagement and minimizes slippage under load.

How does the anodized coating affect performance?

The anodized coating adds a hard, protective layer to the aluminum surface, which helps prevent scratches, oxidation, and chemical damage. This protective layer also reduces friction between the pulley and belt, contributing to quieter operation and longer belt life.

Can I use these pulleys for high‑speed applications?

Absolutely. The lightweight aluminum construction reduces rotational mass, allowing the pulleys to handle high speeds with less vibration. This makes them ideal for rapid‑movement scenarios such as fast‑printing 3D printers or high‑feed CNC machining.

What warranty does JiuWu provide?
