Casing rings
• Made of bronze, cast iron, or Nitronic 60 stainless steel
• Installed with an anti-rotation device
• Designed to restrict leakage across the ring fit
Bearings

• Inboard, or coupling end, bearing: single row ball bearing
• Outboard bearing: double row cylindrical roller bearing, retained by a bearing locknut and lock-
washer
Bearing housing
The bearing housings are bolted to the end of the lower half of the casing and assure positive alignment
of the rotating element.
The housings provide a fit for the inboard bearing that allows freedom for thermal expansion. The out-
board bearing is clamped in place in order to take all thrust loads and to keep the rotating element in its
proper axial location. Openings for adding new grease and draining old grease are provided.

• Steel construction
• Drip pan beneath pump end with tapped drain connection
