Shafts & Bearings

Flygt shafts and bearings are the result of many years of design refinements based on field experience, laboratory testing and advanced calculations using computer programs that analyze and size the rotating system of a pump or mixer. Bearings are one of the key components that determine service intervals for Flygt pumps and mixers, which means that knowledge and understanding of the variety of factors that influence a bearing's lifetime are of outmost importance. A correctly sized pump shaft is fundamental for smooth and trouble free operation with no disturbances from natural frequencies, large shaft deflections or fatigue failures. Knowledge of unpredictable failure causes, such as penetrating fluid in the bearing, assembly damage to the shaft, and so on, are also an important part in our design work.
