18Teeth 2GT Timing Pulley XKLDSFB 6/10mm Belt 3.17mm Bore

Description

Product Overview

The 18Teeth 2GT Timing Pulley by XKLDSFB is a precision‑engineered component designed to meet the demanding requirements of modern additive manufacturing and computer‑numerical‑control (CNC) machinery. Constructed from high‑grade aluminum alloy, the pulley benefits from a surface oxidation treatment that enhances resistance to wear, corrosion, and heat buildup during prolonged operation. Its 18‑tooth GT2 profile provides a consistent gear ratio, ensuring accurate motion control without slippage, while the 6 mm to 10 mm belt width compatibility offers flexibility for a range of belt sizes commonly used in 3D printers, small‑scale milling machines, and gear‑shaping equipment. The bore diameter of 3.17 mm (approximately 0.125 in) aligns with standard GT2 motor shafts, allowing for straightforward installation and secure mounting.

Key specifications include a compact cubic form factor measuring 0.39 × 0.39 × 0.39 inches (approximately 10 mm per side) and a lightweight profile of 1.76 ounces, which minimizes the inertial load on the drive system. The pulley’s fine tooth pitch and smooth surface finish contribute to high transmission efficiency, reducing energy loss and extending the lifespan of both the belt and the motor. Designed with a simple yet robust structure, the pulley can be easily fixed using a set screw or integrated screw hole, facilitating quick assembly, maintenance, and replacement without the need for specialized tools.

Usage

This timing pulley excels in environments where precise, repeatable motion is critical. In desktop 3D printers, it synchronizes the movement of the X‑ and Y‑axes, delivering smooth layer deposition and accurate dimensional fidelity. For CNC routers and milling machines, the pulley drives the spindle or work‑head with minimal backlash, enabling fine detail carving and consistent material removal. The robust aluminum construction also makes it suitable for gear shapers, hobbing machines, and other industrial transmission applications where durability and energy efficiency are paramount.

Installation is straightforward: align the pulley’s bore with the motor shaft, secure it with the provided set screw, and thread the GT2 belt through the pulley’s groove, ensuring the belt sits evenly across the teeth. The design’s tolerance accommodates slight variations in belt width, allowing users to switch between 6 mm and 10 mm belts without replacing the pulley. This adaptability reduces inventory costs and simplifies maintenance for workshops that service multiple machine types. The pulley’s low weight and compact size also help keep the overall moving mass low, which is essential for high‑speed printing and rapid‑positioning tasks.

FAQ

What belt sizes are compatible with this pulley?

The pulley is designed to work with GT2 belts ranging from 6 mm to 10 mm in width, allowing you to use either standard 6 mm belts for compact setups or wider 10 mm belts when higher torque transmission is required.

Can this pulley be used on both 3D printers and CNC machines?

Yes. Its precise tooth profile, reliable slip‑free operation, and robust aluminum construction make it suitable for a variety of motion‑control systems, including desktop 3D printers, CNC routers, milling machines, and gear‑shaping equipment.

How do I install the pulley on my motor shaft?

Align the 3.17 mm bore with the motor shaft, insert the pulley, and tighten the set screw or integrated screw hole to secure it. Then thread the GT2 belt through the pulley’s groove, ensuring even tension across all teeth before final tightening.

Is there a warranty or after‑sales service?

All units are covered by a manufacturer warranty that includes replacement for any defects in material or workmanship. Our technical support team is available to help with installation, troubleshooting, and any customization inquiries you may have.

What makes the aluminum alloy used in this pulley superior?

The alloy is treated with a surface oxidation process that increases hardness and resistance to corrosion while maintaining a lightweight profile. This combination provides high durability, stable performance under temperature variations, and long service life compared to standard plastic or lower‑grade metal pulleys.
