Tsubaki Nakashima NEF25W-NH20JD2XB28P1 Disc Coupling

Description:

The Tsubaki NEF25W-NH20JD2XB28P1 Disc Coupling is used in industrial motion control and power transmission systems to transmit torque while compensating for shaft misalignment without backlash. Commonly installed between servo motors, gearboxes, pumps, compressors, conveyors, and precision manufacturing equipment requiring high torsional rigidity and maintenance-free operation. Maintenance teams and system integrators use this disc coupling for repair, retrofit, expansion, or replacement to restore precise power transmission and minimize equipment downtime.

Applications:

The Tsubaki NEF25W-NH20JD2XB28P1 is an ECHT-FLEX spacer-type disc coupling engineered for high-speed, high-precision applications. Its all-metal construction eliminates the need for lubrication while providing excellent torsional stiffness and the ability to accommodate angular, parallel, and axial shaft misalignment. The coupling is ideal for servo systems, packaging machinery, conveyors, pumps, compressors, machine tools, and other industrial automation equipment requiring reliable, backlash-free torque transmission.
