These 3300 DNR Series pump bearings have been engineered with an exclusive double-row bearing design and a steeper contact angle of 40 degrees to meet the higher thrust demands in ANSI-style pumps. They are especially suitable for pump applications characterized by high axial loads, marginal lubrication and higher operating temperatures, and significant vibration.

Editor's Note: A robust machined brass cage offers improved performance in heavy-duty and poorly lubricated conditions.
