Stronger shaft connections with compact OKCX couplings

The latest generation of oil-injection shaft couplings from SKF enable stronger, more compact shaft to shaft connections to be achieved quickly and simply. The OKCX couplings feature 50% higher torque transmission capacity than conventional designs, providing a safe and cost effective way to reduce the size or increase the torque capacity of your shaft connections.

As the OKCX couplings incorporate SKF’s oil-injection system, they are easy and fast to mount, minimising the cost and disruption of installation. In addition to allowing more compact shaft connections to be achieved, without the need for flanges and bolts, this innovative mounting method also enables more secure, safer coupling.

The inner sleeve of the SKF coupling is coated with carbides utilizing advanced plasma technology. As a result, the OKCX couplings have a friction coefficient of 0.3 rather than the typical 0.14, enabling them to provide considerably stronger, more dependable connections.

The superior torque transmission capacity of the new couplings eliminates the need for expensive reinforcement sleeves where hollow shafts are used. With no need for sleeves, bolts or flanges, straight and compact shafts can be achieved, allowing machine builders and designers considerably greater freedom.

The OKCX couplings are ideal in a wide range of demanding industries, including marine, power generation, pulp and paper, and steel. Tailor-made couplings can also be specified at dimensions of over 100mm, meeting the specific needs of an application.
