SKF S2M Magnetic Bearings for the oil and gas industry - SKF.com
Their extreme precision and stability makes active magnetic bearings suitable for a much wider operating range than conventional bearings. And no bearing friction means there is no need for oil lubrication, a key advantage that simpliies turbomachinery design and reduces maintenance. SKF S2M Magnetic Bearings.

Whether the screw compressor type is dry-running or oil-flooded, the bearings operating within must support rotor loads and help ensure accurate radial and axial rotor positioning. To help improve energy efficiency, the bearing arrangements must optimize rotor head clearance. And they must do so reliably, often at high
