They stay on hard.

And come off easy.

OK Couplings from SKF Steel. More than just OK for high torque and heavy shock load applications. They harness the relentless force of friction to outlast and outperform conventional couplings. Without the need for keyways or thrust rings. No blueing of tapered fits.

OK Couplings stay on hard until you need to take them off. Assembly, disassembly and reassembly takes minutes instead of days. So adjusting shaft length or replacing shaft seals is a breeze. But most importantly, for shaft sizes from 25mm to 1,000mm, there is no stronger coupling in the world.

You'll find the OK Coupling performing in some of the world's toughest places. In 2.5 megawatt wind-powered generators. In fast moving container ships with 60,000 HP per shaft. In ;ce breakers withstanding heavy propeller shock loads. conveyor drives for open-pit mines exposed to the searing desert heat.

Wherever the duty is heavy, there's an OK Coupling that fits. For the principles, performance and world-proven track record, contact SKF Steel Coupling Division,
