Coupling Corporation of America (CCA), founded in 1968, manufactures FLEXXOR diaphragm shaft couplings and the patented Anderson Clamp Hub keyless shaft connections.\r\nFLEXXOR couplings utilize thin stainless steel with holes forming a spoke-like pattern and providing generous angle and axial movement between connected machines. CCA makes quill shafts for torsionally soft spring rate couplings.\r\nCCAs unique keyless hub connections afford high performance friction drives that can be retrofitted on cylindrical or tapered shafts. No heat or hydraulics are needed to apply these hubs.
