Swivel

So how do you deliver rugged reliability swivels? 1) start with “angular contact” bearings, which are designed to handle both thrust and radial loads, 2) the appropriate size and quantity of “angular contact” bearings are then assembled in a stack that provides safe performance at the rated load, 3) within the bearing stack each swivel must have two bearings that are positioned in the thrust (pushback) direction in the event that the product needs to be pushed backwards and finally 4) the sealing system must consist of one shaft seal and two lip seals with steel reinforcing rings to prevent soil and drilling fluid intrusion.
