DFC Series Aluminium Alloy Curved Jaw Coupling – Rotex Jaw Spider Coupling for Motor

Factory Direct | High‑Strength Aluminium Alloy | Urethane Spider | Zero Rotation Clearance | OEM / ODM / OBM | MOQ 1pc

Product Overview

The DFC Series Aluminium Alloy Curved Jaw Coupling is a precision flexible jaw / spider coupling designed for motors, pumps, conveyors, and general industrial drive systems. As a Rotex‑style jaw spider coupling, it features a high‑strength aluminium alloy body and a urethane elastic spider, providing reliable torque transmission, vibration damping, and compensation for radial, angular, and axial deviations.

The DFC coupling offers zero rotation clearance, making it suitable for both positive and negative rotation. Its detachable design and clamping screw fastening method ensure easy installation and maintenance. The urethane spider is highly resistant to oil, dirt, sand, grease, moisture, many solvents, and atmospheric ozone, delivering excellent abrasion resistance and elasticity.

With a 20 mm bore, 100 N·m rated torque, and 1000 RPM maximum speed, the DFC Series is ideal for motor connections, building material shops, machinery repair shops, food and beverage factories, farms, restaurants, home use, retail, and construction works. Custom bores, lengths, and configurations are available to meet your specific OEM requirements.
