Tsubaki NEF04-HUBL-H15JD2 Disc Coupling Hub Set

Description:

The Tsubaki NEF04-HUBL-H15JD2 / NEF04-HUBN-H22JD2 ECHT-FLEX Disc Coupling Hub Set 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, conveyors, compressors, and precision manufacturing equipment requiring high torsional rigidity and maintenance-free operation. Maintenance teams and system integrators use this hub set for repair, retrofit, expansion, or replacement to restore precise power transmission and minimize equipment downtime.

Applications:

The Tsubaki NEF04-HUBL-H15JD2 and NEF04-HUBN-H22JD2 are replacement hubs for the ECHT-FLEX NEF04 Series disc coupling. Featuring keyed bores of 15 mm and 22 mm, these steel hubs provide secure shaft mounting while maintaining zero-backlash torque transmission. When assembled with the NEF04 disc pack, they compensate for angular and axial shaft misalignment without requiring lubrication, making them ideal for servo drives, machine tools, conveyors, packaging machinery, pumps, compressors, and industrial automation systems.
