Product Details

Brand Name

Kop-Flex®

Type

Type EB Finished Bore

Description

When driving and driven shafts are widely separated an unsupported or floating shaft is used to span the gap. The two couplings required at each end of that shaft consist of one half of a standard coupling bolted to a rigid hub, each unit called a flex-rigid coupling. Usually, the rigid hubs are mounted on the driving and driven shafts so that the flex halves on the floating shaft may be replaced without disturbing the connected equipment.
