LX Elastic Pin Coupling – 45# Steel Nylon Pin Flexible Coupling for High Torque & Servo Motor Drives

Factory Direct | H7 Precision Bore | Nylon Elastic Pins | Custom Bores, Keyways & Surface Finishes

Product Overview

The LX Elastic Pin Coupling is a robust and versatile flexible shaft coupling designed for reliable torque transmission, vibration damping, and misalignment compensation. Manufactured with high-quality 45# steel hubs and nylon elastic pins, this coupling delivers high strength, excellent wear resistance, and stable performance in demanding industrial environments.

The elastic element is made of nylon, offering high strength, good wear resistance, self-lubricating properties, lightweight construction, and low noise. It is also suitable for corrosive environments. The steel brake wheel outer surface is quenched for improved hardness and durability. The half-coupling bore and keyway types and dimensions follow GB/T3852-1997, and the two half-couplings can be combined with different shaft hole types as needed.

With an H7 precision bore, the LX coupling ensures a close shaft fit, high concentricity, and efficient power transmission. Its simple structure makes installation and removal easy, reducing maintenance time and cost. The LX series is an ideal choice for CNC machine tools, packaging machinery, metallurgical equipment, photovoltaic systems, woodworking machinery, chemical equipment, semiconductor equipment, printing machinery, railway track equipment, and general industrial drive systems.
