Pump Bearings With An Exclusive Design

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 kidding?in the inactive row.

• An ISO P6 (ABEC 3) precision level for better control of the bearing 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.
