Timing Belt Pulley uxcell 5M-20T-1/2B 1/2in Bore Alloy 20 Teeth

Description

Product Overview

The uxcell 5M-20T-1/2B timing belt pulley is engineered for high‑performance power transmission in demanding industrial environments. Featuring a 1/2in (12.7 mm) bore, the pulley accommodates standard 1/2in shafts and provides a secure fit for a wide range of machinery. Its 20 teeth are precision‑cut from high‑grade aluminum alloy, delivering a lightweight yet exceptionally strong component that resists wear and maintains dimensional stability over prolonged use.

With a 5 mm pitch, the pulley matches the standard 15 mm width synchronous belt, ensuring seamless meshing and eliminating slippage. The integrated keyway simplifies installation, allowing technicians to secure the pulley with a single key and set‑screw, reducing downtime and minimizing the risk of misalignment. The overall dimensions—35 mm outer diameter and 22 mm thickness—provide a compact footprint while delivering the torque capacity required for milling, drilling, hobbing, and other precision machining applications.

Usage

Designed for versatility, this timing belt pulley excels in a variety of industrial settings. It is an ideal replacement part for CNC milling machines where precise timing and repeatability are critical. In drilling stations, the pulley ensures consistent belt speed, reducing vibration and extending belt life. Hobbing machines benefit from the pulley’s accurate tooth profile, which maintains synchronization between the drive and the workpiece, resulting in superior surface finish and dimensional accuracy.

Beyond machining, the pulley can be employed in material handling equipment such as conveyor systems, where reliable power transfer is essential for continuous operation. Its aluminum alloy construction offers a balance of strength and weight, making it suitable for mobile platforms and robotic arms that require rapid acceleration without sacrificing durability. The 1/2in bore also allows easy integration with standard motor shafts, facilitating retrofits and upgrades across a broad spectrum of equipment.
