A scroll compressor of the type having a cantilever mounted shaft is provided with a carbon crankcase bearing. Further, the bearing mounting the eccentric pin within the orbiting scroll is also formed of a carbon material. The bearing mounting the lower end of the shaft is further formed of the carbon material. The carbon bearing insures that the shaft will be quickly worn away should there be shaft misalignment.
