Product Description
DFCS Elastic Jaw Coupling – 45# Steel Clamp Type for Servo Motor & Ball Screw
Factory Direct from Guangdong, China | 45# High-Quality Steel | Clamp Type (Split-Hub) | Zero Backlash | H7 Precision Bore | 12.9-Grade Screws | Imported Polyurethane Spider | E‑LDCK11 / MFS01 Compatible | Rotex Replacement | Custom Bores Available
Product Overview
The DFCS Elastic Jaw Coupling from Apexcoupling is a high-precision, flexible shaft coupling designed for reliable torque transmission, vibration damping, and misalignment compensation. Manufactured in Dongguan, Guangdong, China, this clamp-type jaw coupling is an ideal solution for servo motors, ball screws, encoders, and other precision drive systems. It is also a direct replacement for E‑LDCK11, MFS01, and Rotex style couplings.
The coupling features 45# high-quality steel hubs with a clamp-type (split-hub) mounting and 12.9-grade high-rigidity screws (nickel-plated or blackened). The imported polyurethane spider offers excellent wear resistance, oil resistance, electrical insulation, and a wide adjustable performance range. The H7 precision bore ensures high concentricity and a secure shaft fit, while the zero backlash design makes it suitable for both forward and reverse rotation.
With its detachable design, installation and maintenance are quick and easy. The coupling absorbs vibration, compensates for radial, angular, and axial misalignments, and provides reliable, long-life performance. The 3D chamfered edges prevent hand injuries, and every bore is 100% inspected with plug gauges to ensure precision. Produced on German-imported high-precision machining centers, the DFCS coupling meets export-quality standards and is a reliable alternative to imported ROTEX series couplings.
