Product Description

Aluminium 8 Type High Torque Encoder Flexible Coupling – DB Series

Factory Direct from Guangdong, China | High‑Strength Aluminium Alloy | 8‑Shaped Design for Encoders | Polyurethane Elastomer | 4–17mm Bore | 6000 RPM | 3‑Year Warranty | OEM / ODM

 


Product Overview

The Aluminium 8 Type High Torque Encoder Flexible Coupling (DB Series) is a precision‑engineered flexible shaft coupling designed specifically for encoder applications. Manufactured by Apexcoupling in Guangdong, China, this coupling features a unique 8‑shaped structure that provides excellent flexibility, high torque capacity, and reliable performance in motion control systems.

The shaft sleeve is made from high‑strength aluminium alloy, offering a lightweight yet durable solution for encoder connections. The polyurethane elastomer is oil‑resistant and oxidation‑resistant, ensuring long service life even in demanding environments. The 8‑shaped design provides good flexibility and prevents breakage, making it ideal for applications where misalignment and vibration are present.

With a bore diameter range of 4–17mm, a rated torque of 0.5–2.25 N·m, and a maximum speed of 6000 RPM, this coupling is suitable for a wide range of encoders and small motors. The jaw/spider structure ensures smooth torque transmission, while the flexible design compensates for radial, angular, and axial misalignments. Backed by a 3‑year warranty and full OEM/ODM support, the DB Series coupling is the reliable choice for encoder applications in home use, automation, and precision equipment.
