Product Description

The 4 RKF 40-xM Coupling is a precision-engineered Flexible Shaft Coupler designed for high-torque transmission in industrial machinery. Part of the Series 40M Flange Coupler family, it features a robust flange design with dual input/output connections, enabling direct integration with servo motors, gearboxes, and driven equipment. Operating within a temperature range of -40°C to +120°C, this coupling accommodates shaft misalignment up to 3° angular and 0.5mm radial. Its stainless steel construction ensures durability in harsh environments like robotics, CNC machinery, and pump systems. Key advantages include zero-backlash performance, torsional rigidity, and vibration damping, though precise alignment is critical for optimal operation. The compact design supports torque capacities up to 400 Nm, with flange diameters standardized for seamless compatibility across industrial drive systems.
