Description

ECHT-FLEX Coupling (Disk Couplings ):Flexibility, high rigidity, lubrication-free Disk Coupling generates axial force on a bolt by tightening a U-nut and transmits torque by frictional force between hub, washer and disk. No service life caused by wear with no sliding parts, and designs below fatigue limit, so can be used for a long period of time. No backlash with friction transmission, high torsional rigidity, and lube-free operation makes it ideal for coupling servo motors, stepping motors, etc. Tsubaki Disk Coupling, Echt-Flex Coupling uses discs with an optimal shape through finite element analysis, reliably transmits torque while smoothly absorbing misalignment. Lineup includes NER series with original center unit structure that eliminates troublesome disc assembly at the worksite, NES series for small precision applications, general-purpose NEF series with its extensive line-up, and NEH series with large capacity. ※The discs are not consumable parts. If the disc is damaged, there may be some trouble such as overload, excessive mounting error (misalignment), etc. The disc coupling has no wear life because of friction transmission. NER series with built-in discs that are easy to assemble should be considered. ※Normally, consider the spacer type. The single type cannot absorb eccentricity (parallel misalignment).
