The system consists of a top swivel and bottom swivel.
Top Swivel: The top swivel uses 4mm ball bearings to minimise friction.
Lower Swivel: The unit is manufactured from glass-filled composite
with molded-in stainless steel reinforcement. It also has twin bearing units with 4 mm stainless steel ball bearings. These larger ball bearings run in multi-axis bearing units to reduce friction and wear.
