A compressor having a housing and mutually engaged stationary and orbiting scrolls. A crankcase is disposed between a motor and the orbiting scroll. A shaft is operably connected with the orbiting scroll and extends through the crankcase and the motor. The end of the shaft extending from the motor is rotatably supported by a bearing mounted in a bearing support. A counterweight is rotationally coupled with the shaft proximate the bearing support. An oil sump is disposed within the housing and an oil shield is fixed to the bearing support. The oil shield has a cylindrical portion with an open end which encircles the counterweight and may include a plurality of flexible members having inwardly bent portions which engage a groove on the bearing support.
