Rigid Couplings

John Crane’s Metastream® rigid couplings are developed to remove the misalignment and unbalance caused by axially split clam shell couplings on your equipment. They are designed with radially locating pilots for excellent runout between equipment shafts that help reduce unbalance and vibration in your system. These designs also come with external adjustment holes to make setting the position of your pump impeller as easy as possible. Rigid couplings are often used on vertical motor to pump packages where there is no thrust bearing in the pump, meaning the weight of the pump shaft and impeller will be supported by the coupling.​
