Flanged flexible coupling

Flanged flexible coupling

CL100～355 (standard products). They have the characteristic of not transmitting machine vibrations and shaft runout to the opposite side.

We handle "flanged flexible couplings" that can smoothly transmit shaft power. By removing the coupling elements (coupling bolts), it is possible to rotate each machine's shaft separately for checking the rotation direction and for standalone operation of the prime mover. For sizes not listed in the catalog, we can accommodate them as made-to-order items. Additionally, all SCL products are made-to-order. 【Features】 ■ Smoothly transmits shaft power ■ Does not transmit machine vibrations or shaft runout to the other side ■ No thrust force exerted on the shaft from the coupling ■ Allows manual rotation of the rotating shaft from the outside while directly connected ■ Easy to measure the direct connection state of the machine (relative position of both shafts) ■ Simple structure and completely flexible *For more details, please download the PDF or feel free to contact us.
