SKF Steel Introduces New Simplified Coupling

—Literature Available The Coupling Division of SKF Steel, with headquarters in Avon, Conn., has developed the OKF coupling to fulfill the need for a simplified method of connecting a shaft to a flanged prime mover or gearbox output. This coupling connects a cylindrical shaft without taper or keyway to the output flange, reducing maintenance time and costs, and saving installation problems associated with tapered fits and fitted keyways.

The OKF coupling is similar to the OK shaft coupling that, unlike other rigid couplings available on the marketplace, uses no bolts, nuts, keys, or keyways. Instead, it employs a powerful interference fit to transmit high torque and shock loads—an interference fit that is created without using heat to expand the components.

The design of the OK coupling requires no keyways in the shaft, and enables a 25-percent reduction in shaft diameter to be made with considerable material savings in other components such as bearings and seals. Corresponding weight savings are also realized. Simple fine-turning is all that is required to prepare the shaft.
