Ball Bearings handle centrifugal pump applications.
Press Release Summary:
PumPac® Ball Bearings feature combination of 40° and 15° contact angles capable of carrying high thrust loads. Machined bronze cages are wear-resistant for use in poor lubrication conditions. ABEC 3 tolerances promote smooth operation, while V-etched OD enables simplified installation by indicating direction of thrust-carrying capability. Applications include centrifugal pumps, large vertical electric motors, compressors, and centrifuges.

PumPac® Angular Contact Ball Bearings
FEATURE INTERNAL DESIGN OPTIMIZED FOR APPLICATION DEMANDS
All three series of PumPac® angular contact bearing arrangements available from MRC Bearing Services (Kulpsville, PA) serve as ideal solutions for centrifugal pump applications. These bearings are uniquely arranged to reduce operating temperatures and vibration levels for smoother operation and longer service life in difficult centrifugal pump conditions.
Standard PumPac features and benefits include combination of 40º and 15º contact angles capable of carrying high thrust loads with the 40º bearing (without unloading the opposed 15º bearing); industry-preferred machined bronze cages highly wear-resistant for optimum functioning in poor lubrication conditions; "CB" endplay for better ball control and reduced heat generation and operating temperature; ABEC 3 tolerances promoting less impeller shaft runout, smoother operation, and longer seal life; and V-etched OD to enable simplified installation by clearly indicating direction of thrust-carrying capability.
Applications for the PumPac 8000 Series include centrifugal pumps, large vertical electric motors, compressors, centrifuges, and other applications subject to thrust loads while operating at relatively high speeds; the PumPac 8000BB Diamond Series is designed for centrifugal pumps and motors where the thrust loads are light and radial loads predominate (such as in double-suction pumps and pumps with closed impellers); and the PumPac 8000AAB Triplex Series is ideal for pumps involving very heavy primary thrust loads.
MRC further develops made-to-order (MTO) warranted products through a dedicated MTO program established to meet customized application demands. CAD drawings of standard products are available for downloading free from the Web site.
