Application: Refrigeration/ NH3 High Stage compressor Compressor Model: Mycom model 200LUD-MX
Thrust bearing problems are the most common problem found in screw compressors. In this case study the compressor is presumed to have run for more than 70,000 hours (Hour meter broken). The thrust bearing used was a double-row angular contact spherical ball thrust bearings located on each rotor.
Damage occurred on the inside bearing of the male rotor. This was a typical failure pattern for compressors with long operating hours.
