The shaft includes a wear-resistant sleeve-like treatment on at least a portion of an outer surface of the shaft adjacent the bearing. The lubricant is POE oil or a lubricant blend composition that includes two or more lubricants, the two or more lubricants including a first lubricant and a second lubricant.

Refrigerant compressor with wear sleeve and lubricant blends for handling debris-laden fluids

A compressor including a housing, a shaft configured to be rotated relative to the housing to compress a refrigerant, a motor configured to drive the shaft, a lubrication system configured to supply lubricant to the compressor, and a bearing configured to support the shaft. The shaft includes a wear-resistant sleeve-like treatment on at least a portion of an outer surface of the shaft adjacent the bearing. The lubricant is a lubricant blend composition that includes two or more lubricants, the two or more lubricants including a first lubricant and a second lubricant. The first lubricant is present at a higher volume percentage than the second lubricant, and the first lubricant includes a higher viscosity than the second lubricant.
