The FORM-FLEX coupling has no sliding, frictional, or rolling parts, so no lube oil is required.
Maintenance-free “FIT & FORGET”
Lightweight and high torque
A wide range of allowance for misalignment
Small thrust load and bending moment
Backlash-free and high torsional rigidity
Excellent environment resistance
Tough construction and low load stress
Easy installation and removal
Failsafe mechanism


This is the first flat spring type small precision coupling developed in Japan. This flat spring, which is the key component of the coupling, reflects our expertise in thin plate precision processing gained over half a century.
Backlash-free
High torsional rigidity
Large torque capacity
Large absorption of eccentricity and angular deviation
Maintenance-free and long life
Flexible applicability of each part
