Contact angles provide benefits for these bearing arrangements

| By Chemical Engineering



The MRC PumPac series of angular contact ball-bearing arrangements (photo) can reduce operating temperatures and vibration while helping to prevent ball sliding and shuttling in demanding pump applications, including centrifugal pumps and other systems typically subject to significant thrust loads while operating at relatively high speeds. PumPac arrangements incorporate combinations of 40- and 15-deg bearing contact angles capable of carrying high thrust loads within the 40-deg bearing without unloading the opposed 15-deg bearing. As a result, greater axial loads can be applied, and the bearing’s operating temperature and vibration levels will decrease for smoother operation and longer service life, says the company. — SKF USA Inc., Lansdale, Pa.
