Flexible coupling: stainless steel disc coupling
Ruland Manufacturing Co., Inc.
The single disc coupling is comprised of two black anodized aluminum hubs and multiple flat stainless steel disc springs. The single disc coupling is not very adept at accommodating parallel misalignment due to the complex bending of the disc that would be required.
The double disc coupling consists of two black anodized aluminum hubs, multiple flat stainless steel disc springs and a rigid center spacer. The double disc coupling allows each disc to bend in the opposite direction to harness the parallel offset.
