As the HDD industry has grown, so has our line of swivels. Our newest introduction to the family is an impressive 60-ton swivel available in either BOX X CLEVIS or CLEVIS X CLEVIS configurations. This Heavy-Duty swivel weighs in at 365-pounds, measures 10” in diameter and is 29” long.
In the process of developing industry specific swivels, StraightLine engineers led the way in the development of bearing and sealing systems that have proved to thrive in harsh underground environments. Over the years it has become evident that our original designs have stood the test of time and continue to deliver rugged reliability. So how do you deliver rugged reliability? 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 1 shaft seal and 2 lip seals with steel reinforcing rings to prevent soil and drilling fluid intrusion.
Our exceptionally crafted swivels are off the shelf available in 5-ton, 15-ton, 20-ton, 30-ton, 45-ton & 60-ton sizes. Quality, rugged-reliability and our commitment to continue to exceed industry standards – that says it all about StraightLine’s complete line of swivels.
