Tilt Pad Journal Bearings

Dynamic conditions of high-speed axial and centrifugal compressors often necessitate the use of tilting pad journal bearing technologies. Design features such as ‘Directed Lubrication’ and specialized materials such as copper chrome (CuCr) backing allow us to maximize efficiency.

tilt pad thrust bearing with 'Directed Lubrication'

Tilt Pad Thrust Bearings

Waukesha Bearings tilt pad thrust bearings, available in non-equalizing and self-equalizing designs, handle high axial loads with minimal power loss. As with journal bearings, ‘Directed Lubrication’ and CuCr back pads are commonly specified.

Polymer Bearings for Thin Film Lubrication

An upgrade to polymer bearing materials may allow lubrication by water or other thin films.

In screw compressors where refrigerant has reduced the oil viscosity, polymer bearings can continue to support high thrust loads despite the thin film.

In axial compressors, polymer bearings can allow for water lubrication, eliminating the potential for oil to contaminate the compressed product and simplifying the sealing components.

Related Case Study

Over a 13-year span, a major South American oil company’s maintenance department fought recurring high vibrations in three gas reinjection compressor trains. A thorough analysis of the compressors and an inspection of damaged components led to a two-part solution. Since the implementation, the compressors have exhibited low vibration levels and overall efficiency has increased.

Stability for Compressor Station Refrigeration Process

At a compressor station in West Siberia, a refrigeration process applied to the gas at the plant outlet created a requirement for a high efficiency compressor. That efficiency was achieved with a rotor shaft with a high slenderness ratio, resulting in a very flexible shaft. The industry-leading processing power and advanced control algorithms used by Waukesha AMB controllers were required for the successful operation of these machines.
