Description
Large Bore Swivel Joints
Large bore Swivel joints feature either 1 or 2 ball tracks of ball bearings, enabling 360° rotation without any problems, despite simultaneous external loading through force and torque.
If you are looking for a Swivel to take severe loads or in a size greater than 48″ please see our Engineered Swivel Joint.
Materials
The standard large bore swivel joints are normally produced in carbon steel (St52-3, 42CrMo4), stainless steel (1.4571), and also aluminium. Further stainless steels (1.4301, 1.4404) and materials such as Duplex, Super Duplex and Hastelloy are also available on request.
