Key Roles of Inboard Bearings And Spacers in Centrifugal Pumps

Key roles of inboard bearings and spacers in centrifugal pumps include:

Reducing friction: Bearings facilitate the smooth rotation of the pump shaft and are crucial for minimizing frictional losses.

Aligning rotating elements: Properly aligned bearings help maintain concentricity of the shaft, which is vital for balanced operation and to prevent vibration and wear.

Handling radial loads: The inboard bearing may handle radial loads imparted by the rotation of the impeller.

Maintaining clearance: The spacer ensures there is proper clearance between the impeller and the pump casing, which is essential for the pump’s performance and efficiency.

Thermal expansion: In some cases, spacers allow for controlled thermal expansion of the pump's rotating elements so that clearances and alignments remain within designed tolerances despite temperature changes.
