The Jabsco 2603-0000 is a genuine Jabsco replacement bearing for Jabsco pumps that list this part. Bearings support the pump shaft and keep it running true, which protects the seal and keeps the impeller centered in the pump body.
A worn bearing shows up as noise, roughness, heat or play in the shaft, and it will quickly destroy seals and impellers if not replaced. Replacing bearings during a rebuild, especially after a seal leak has let water reach them, restores smooth, quiet operation and long pump life.

Frequently Asked Questions
Q: How do I know the bearings are failing?
Grinding or whining noise, heat at the bearing housing, rough rotation or side play in the shaft are common signs.
Q: Why do bearings fail early?
Water from a leaking seal, belt tension that is too tight and misalignment are the usual causes.
Q: Should I replace the seal at the same time?
Yes. A leaking seal often causes bearing failure, and a new seal protects the new bearing.
Q: Do I need a press to install it?
Many bearings are press fit. A small arbor press or proper driver avoids damaging the new bearing.
