Twin screw process gas compressors

Caustic conditions for bearings

Used to boost natural gas line pressure over thousands of miles of pipe, twin screw compressors provide a more efficient alternative to reciprocating compressors.

As with all twin screw designs, the bearings within must support rotor loads and help ensure accurate radial and axial rotor positioning – reliably, with low friction and low noise. Given that the gas that emerges from the wellhead can be caustic, twin screw gas compressor bearings must also be quite corrosion-resistant.

SKF can help

Informed by extensive experience in the oil and gas industries, SKF offers a range of bearing solutions developed for corrosive environments. Super-corrosion-resistant bearing steel, advanced cage materials, plus various coatings and surface preparations are available to help extend bearing life and compressor reliability.
