Polymer bearings incorporating a PTFE-based running surface were viewed as a step forward in scroll compressor performance when they were initially introduced around three decades ago. These polymer ...

Conventional compressor bearings - for example, leaded-bronze, rolling element or bi-metal bushings - will be significantly affected by wear in marginally lubricated environments at bearing locations ...

Approach provides way for designers to assess losses in the driving bearing in compressors and optimize their efficiency ...

Contractors familiar with oil-lubricated compressors may want to start thinking magnetically. Turbocor, from Montreal, PQ, Canada, is introducing a compact centrifugal compressor that uses magnetic ...

A good digital multimeter (DMM) is key to diagnosing compressor problems in general. For instance, in a previous article (May 15 issue of The NEWS) we discussed using the DMM to read suction and ...

Feed holes or grooves typically locate in the top half of a bearing which is characterized by large annular clearances and low internal oil pressures. In split bearings, two grooves are placed at the ...
