Product Description

[Features]
· Oldham type flexible coupling.
· FCD400 used in spacer.
· Ideal for low speed / high torque specifications.
· Grease applied between hub and spacer to prevent burn-in.
· Due to hub and spacer slip, large eccentricity / deflection angles are allowed.
· The protrusion (resin pin) provided on the spacer allows the angle of deviation without difficulty.
· Long-term maintenance-free.
· Grease accumulated in the grease hole gradually leaks during operation, to maintain long-term lubrication performance.
