The Topdrive/Swivel supports the weight of the drill string, while simultaneously acting as a rotating passageway to permit drilling mud to flow into the drill string. The top drive, additionally, provides the torsional force needed to turn the drill string. This application requires high reliability and resistance shock loads generated during the drilling process.

The solution: Schaeffler provides high capacity solutions resistant to potential spike loads possible with this difficult application. We can also work to better

understand the stresses developed during periods of high load. These stresses can be minimized by carefully analyzing both the bearing design and structural
