Description

It is a metal membrane coupling that attaches flexible elements made from multiple layers of thin stainless plates between the hub and the spacer, and assembles it with a reamer bolt to transfer power. It is also a structure that absorbs the shock if a misalignment occurs during the axial connection with the disc element. It is a simple structure with excellent durability and can transfer large-capacity torque, so it is applied to various industrial fields.

Performance

No lubrication

No lubrication injection
required

Low weight

It’s less weight, so it’s
effective for moving.

Transfer

Excellent torque transfer
capability

Misalignment

Excellent absorption of
misalignment

Zero backlash

Zero backlash is possible when
connecting axes.

Hardness

Excellent torsional rigidity

Available

Available at high speed,
high temperature

Power transfer

Power transfer by the reamer
bolt even if the disc is damaged
