Rigid Flange Couplings

Rigid Flange Couplings are commonly employed in the assembly of large, straight shafts where tight tolerances on alignment must be maintained. These couplings are very common in the power transmission industry and are made up of two separate flanged halves that are bolted together. The halves are keyed to the shaft with tapered keys to ensure proper alignment and a tight fit. A rigid flange coupling is often employed in situations where a strong coupling is required, but little axial distance is available.
