SKF has engineered the 3300 DNR Series pump bearings with an exclusive double-row bearing design and a steeper contact angle of 40° to meet the higher thrust demands present in ANSI-style pumps. The pump bearings also offer:

Ideal suitability for pump applications characterized by high axial loads, marginal lubrication, higher operating temperatures and significant vibration due to operating conditions like cavitation.

A robust machined brass cage for improved performance in heavy-duty or poorly lubricated conditions.

Standard axial and internal clearance ranges in order to promote load-sharing between the 2 rows of balls for cooler operation, reduced lubricant degradation and minimized risk of destructive “skidding” in the inactive row.

An ISO P6 (ABEC 3) precision level for better control of the bearing’s mounted clearance.

Availability of standard double-row pump bearings with a range of seals, shields and snap-ring options.

The option of customization to satisfy particular application requirements.

The capacity for retrofitting, so users can realize upgraded bearing performance equivalent to a paired bearing arrangement without the cost of modifying a pump.
