TSUBAKI NEF10-HUBN-H19JD2 Disc Coupling Hub Set

Description:

The Tsubaki NEF10-HUBN-H19JD2 / NEF10-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 NEF10-HUBN-H19JD2 and NEF10-HUBN-H22JD2 are replacement hubs for the NEF10 Series ECHT-FLEX disc coupling. Featuring keyed bores of 19 mm and 22 mm, these hubs provide secure shaft mounting while maintaining zero-backlash torque transmission. Their all-metal construction eliminates the need for lubrication and accommodates angular, parallel, and axial shaft misalignment, making them ideal for servo drives, machine tools, conveyors, packaging machinery, pumps, compressors, and industrial automation systems.
