The sub-sea screw pumps operate in extreme conditions that test the performance limits of standard steel, journal, and magnetic bearings.

SKF (Kulpsville, PA) has announced the availability of its specialized bearing solutions for sub-sea screw pumps, which help enable oil extraction as low as 3,000 meters in a single-step process. The sub-sea screw pumps operate in extreme conditions that test the performance limits of standard steel, journal, and magnetic bearings. They feature:

• A unique arrangement and advanced materials.
• 2 CARB bearings to accommodate shaft deflection and axial displacement.
• A 4-point angular contact ball bearing used to locate the shaft axially.
• Bearings constructed from a super-tough stainless steel, which features high amounts of nitrogen for superior fatigue and corrosion resistance.
• NoWear, coated stainless steel rolling elements.
