GGB Presentation Focuses on Plain Bearings for Scroll Compressors

GGB’s Michael Kim, Derek Marsella and Benoit Sidot made a presentation on “The Evolution of Polymer Bearing Processing for Scroll Compressor Performance and Life Enhancement” July 12 at the 2016 Purdue University Compressor Engineering Conference. The presentation included the history of metal-polymer bearings in compressors, experimental materials, polymer processing methods, test procedures and results, and conclusions. GGB DU bearings were first used in scroll compressors in 1987 to improve a compromised lubrication state. Since then, a number of new polymer bearing materials have been developed. These include DP31 with a powder-based PTFE sliding layer and implemented in scroll compressors in 2009, slurry-based DP10 and film-based DTS10, both of which were first used in scroll compressors in 2010.
