Angular Contact Ball Bearings

PumpPac angular contact ball bearings reduce operating temperatures and vibration levels for smoother operation and longer life.

Available in three series, the bearings incorporate combinations of 40 and 15° bearing-contact angles capable of carrying high thrust loads with the 40° bearing (without unloading the opposed 15° bearing).

Wearresistant machined bronze cages work in poor lubrication conditions. "CB" endplay better controls and lowers operating temperature. ABEC 3 tolerances promote less impeller shaft runout, smoother operation, and longer seal life; and a V-etched OD simplifies installation by clearly indicating the direction of thrust capability.
