OILCO 857-F Series 4 in. Carbon Steel Heavy Duty Riser Swivel Joint

Description

Engineered and manufactured to support the multitude of counter weighted hose loaders outfitting the west coast terminals throughout California. Due to the high moment loads on larger loading assemblies, the 857-F incorporated Timken® tapered roller bearings in the mechanical chamber. This allows for he intense bending moment at the riser and resolves all associated fatiguing issues at the base.
