HYDRAULIC SWIVEL JOINTS for Foundation Boring Drilling
Hydraulic Swivel Joints for Drilling Systems
These are good sized hydraulic turning joints with a low number of passages, capacity and reduced pressure. The main characteristics are the large diameter central pass-through hole and the high rotation speed.
They have a high grade of protection against infiltration of external agents such as sand, mud, water, etc. The following are a few examples:
