Oma make romaflex pin flexible bush-style design couplings provide reliable means of mechanical power transmission giving a constructive and cushioned drive protecting against unavoidable misalignment and help in reducing damage due to regular usage of the connecting parts. The coupling absorb shock torsional loads and vibrations and take all forms of misalignment angular, Offset and angular offset including axial float of shafts. The coupling are constructed with high grade power transmitted, Cast iron from one half to other through steel pins precision machined passing through specially bonded rubber bushes. The elastic properties of rubber bushes enable the connector for take torsional vibrations, Shock loads and misalignment romaflex couplings can be operated in either direction require no lubrication and are unaffected dust and, By water atmospheric conditions.
