Product list (SAFETY FIT®) | We support the world’s industrial base by supplying products, such as rolling stock parts, universal joints and heat exchangers, to railway operators and iron manufacturers

SAFETY FIT® (rigid coupling)

After the mill roll is attached to the drive shaft, the rigid coupling is hydraulically expanded to stick to the mill roll shaft. As a result, the gap between the drive shaft and the mill roll is eliminated, and the eccentricity of the mill roll is reduced.

At the time of mill roll replacement, the hydraulic pressure of the rigid coupling is released so the coupling will shrink for easy replacement work.

Supported shaft diameter

30-720 mm

Maximum transmission torque range

0.3-372 kN・m

SAFETY FIT® (hydraulic expanding torque limiters)

SAFETY FIT is a safety device that blocks torque transmission by relieving hydraulic pressure and running idle when the load torque exceeds its set value.
