Pin & Bush


B-Flex couplings consist of a set of resilient BARREL Shaped bushes with pins & nuts and two flanged hubs of graded cast iron.
The special BARREL shaped bushes permit the MISALIGNMENT IN ALL DIRECTIONS and give extra torsional flexibility as compared to plain bushes. These couplings are suitable for general engineering applications requiring reliable power transmission even under conditions of shaft misalignments which are often unavoidable. Special Bushes provide stiffness characteristics, absorb effective shocks, torsional vibrations and accommodates misalignments.
