For tough applications where strength and affordability are important, the steel design of rigid compression couplings is well suited. Timken cast steel couplings are an excellent choice for joining two shafts of the same size. This type of coupling is also known as a “rigid clamp style” coupling.
Choose from standard sizes for shafts 1-7/16″ through 5″. Custom sizes are available upon request.
