Significantly reduce assembly time with ECHT-FLEX couplings NER series
No assembly of the disc is required, and no disc replacement is required during maintenance.
Tsubaki's unique center unit structure
Conventional disc couplings required users to assemble the disc portion themselves, but the NER series employs a center unit structure that integrates the disc, spacer, and flange, and is shipped pre-assembled, eliminating the need for user assembly.
advantage
- -No need to assemble the disc on site.
- - Can be tightened with a small torque wrench.
- - No more washer mix-ups or lost parts.
Unnecessary man-hours can be reduced. - - Can accommodate large shaft bore diameters.
- - During device maintenance, the disk section does not need to be disassembled.
Removable.
After centering, simply tighten the bolts to complete the fastening.
*Torque management is required using a torque wrench.

Torque transmission mechanism in the NER series
Torque is transmitted by friction
Tightening the U-nut generates axial force in the bolt, and torque is transmitted by the friction force between the hub, washer, and disc.
Because it has no sliding parts, it can be used for a long time.
There is no need to replace the disk during maintenance.
