Oberdorfer 1P Bearing – OEM Pump Replacement Part
Oberdorfer offers bronze bearings with grease fittings and heavy duty carbon bearings that are self lubricating, depending on the pump family. The 1P is the factory part for its position in that range.
Where the bearing is grease lubricated, the grease schedule matters. Too little and it runs dry, too much and it runs hot, and both end at the same place.
Inspect the shaft seat and the housing bore when the old bearing comes out. A spun race leaves a seat that will not hold the new bearing tight.

Frequently Asked Questions
Q: Why did the bearing fail so soon after a rebuild?
Check the seal and the alignment. A leaking seal or a misaligned coupling will take out a new bearing quickly.
Q: Is a noisy bearing urgent?
Treat it as urgent. Once a bearing is audible it is already damaged, and continuing to run it risks the shaft and the housing.
Q: Does this bearing need greasing?
It depends on the pump. Carbon bearings in this range are self lubricating; bronze bearings with a fitting are on a grease schedule.
Q: Can I fit it without a press?
It is better not to. Driving a bearing on with impact loads the rolling elements and shortens its life before it has turned once.
