Grease will not properly lubricate a spindle running at high speed on Babbitt. With that said, some slow speed babbitt bearings will operate fine with grease. However, do not assume that just because the babbitt bearings on your machine were acquired with grease fittings that the machine was intended to run on grease.

Abstract. Lubrication characteristics can greatly affect the service performances of ball bearings. To further clarify the variation law of oilair distribution in bearing cavity, a new simulation method combining the dynamic and computational fluid dynamics (CFD) models is presented. The relative motion between the ball and the cage caused by the cage clearance is obtained by the dynamic ...

Each type of bearing design has a unique removal process. Regardless of the bearing type, the bearing must be removed with extreme care. If done incorrectly, you can damage the bearings, shafts or housings, requiring expensive repairs. For smaller bearings, there are a variety of pullers available to assist with bearing removal (Fig. 1).
