SJW swivel joints are designed for fabrication of loading arms and pipe work requiring up to 360º rotational joint.

They are available machined from steel or aluminium with pre-prepared ends 100mm (4”) or 75 mm (3”) for welding directly to pipe or tube.

A cost-effective way of achieving a rotating joint, for loading arms or other machinery requiring swivelling joints.

This swivel incorporates the well-known high load, low wear Liquip principle of ball with needle bearing combination used exclusively throughout Liquip loading arms.

Sealing is provided by a Viton or nitrile primary face V-seal, and two viton O-Rings which isolate the bearing pack from the product.

Any ingress past a worn primary seal is contained by the secondary o-ring, before the product contacts the bearings. Any leak is also immediately visible from a telltale weep indicator hole (initially supplied with a plug fitted).

The greasing system is the Liquip trademark grease relief system to ensure correct lubrication, by ejecting old grease and particles that can cause wear.

Liquip recommend re-grease at maximum six-month intervals depending on service environment.
