Stafford Manufacturing
This company’s dual-keyed rigid couplings (photo) feature axial and annular keyways to provide additional security for high torque and axial-load applications. The couplings are suitable for heavy, suspended loads on shafts used in mixers, pumps, fans and related drive systems. Designed to prevent axial and radial slippage with higher loads for a given bore size, they are available in diameters from 1 to 5 in. with straight-through or stepped bores for accommodating different diameter shafts. The couplings can be machined from high-temperature alloys, steel, stainless steel or aluminum. These rigid couplings are well-suited for connecting supported shafts and for mixers with unsupported shafts and both new and retrofit power-transmission applications. — Stafford Manufacturing Corp., North Reading, Mass.
