Pump Bearing Life - CR4 Discussion Thre

Now, my humble understanding is that if bearings are sealed for life, they cannot be re-greased, and since grease has limited shelf life (say 2 years), it is impossible for such bearings to last for 10 years. So the specs statement is contradictory. Bearing life of 100,000 hrs applies only to those types with re-lubrication facility.

Using these greases in sealed lifetime lubricated bearings will virtually eliminate bearing failures attributable to lube application errors. Greased-for-life PFPE-filled bearings will also eliminate the cost-of-labour component of periodically re-lubricating bearings. References.

For fitment into the stuffing box of a centrifugal pump. A spiral-groove is cut on the outer surface of the rotor of a pair of tapered bearing surfaces. The groove is 0.02 mm deep, 2 mm wide, and its circumferential length is 50 cm. Barrier-liquid is fed to an entry-mouth of the spiral-groove, and groove generates a pressure in the stuffing box high enough to overcome process pressure.

Bearing Lubrication - Bearing Lubricant Methods | AST Bearin

Miniature and instrument bearings are often only lubricated once for the life of the bearing, making the choice of lubricant critical. Larger bearings are subject to re- lubrication as part of the machinery maintenance cycle. These bearings are often lubricated via oil recirculation systems that are designed into the machinery or equipment.
