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.
