ROMA make ROMAFLEX pin bush type flexible couplings provide reliable means of mechanical power transmission giving a positive and cushioned drive protecting against unavoidable misalignment and help in reducing wear and tear of the connecting parts.
The coupling absorb shock loads, torsional vibrations and take all forms of misalignment: angular; offset and angular offset including axial float of shafts.
The coupling are made out of high grade Cast Iron, power transmitted from one half to other through steel pins precision machined passing through specially bonded rubber bushes. The elastic properties of rubber bushes enable the coupling to take shock loads, torsional vibrations and misalignment
ROMAFLEX couplings can be operated in either direction require no lubrication and are unaffected by water, dust and atmospheric conditions.
The couplings are easy to assemble and give year of trouble free life with minimum maintenance.
Advantages for Flexible Pin Bush Couplings
