Abstract
A scroll compressor is provided within a sealed housing. Although the invention is shown with regard to a scroll compressor, it should be understood that aspects of the invention have benefit to any type sealed compressor. A lower bearing is attached directly to a housing end cap. The lower bearing is easily and accurately attached to the end cap, and reduces the complexity and cost of assembly of a sealed compressor. In particular, the end cap is provided with upset portions spaced circumferentially by gaps. The bearing is secured to the upset portions by welding. Oil can flow through the gaps and into a space beneath the bearing such that it can reach oil passages in the shaft.
