Pump Bearings With An Exclusive Design

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¡ã 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.
