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 ...

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 ...

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 ...

One of the newer technologies involves twin screw compressors. This article will look at service-related aspects of such a unit. The screw compressor is a positive-displacement rotary mach-ine.

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 ...
