Ball bearing — Water Pump, Impeller-end
Ball bearing — Water Pump, Impeller-end
Application: EMD water pump assemblies — impeller end
Part of our Water pump product line
The Ball Bearing — Water Pump, Impeller-End is identified by EMD Part No. 908415 and DLW Part No. 16150405. EMD water-pump parts references specifically identify 908415 as the Ball Bearing for the Water Pump Impeller End, while Indian Railways vendor documentation cross-references EMD 908415 with DLW 16150405. The bearing is included in the EMD water-pump repair kit and is used as part of the water-pump assembly. For procurement and maintenance, the bearing should be identified using the correct EMD and DLW part numbers and the applicable pump configuration.
How This Part Works
The Ball Bearing — Water Pump, Impeller-End supports the impeller-end of the water-pump rotating assembly. It allows the associated rotating components to operate with controlled friction and supports proper shaft rotation within the water-pump assembly. Correct bearing condition is important for maintaining smooth and reliable water-pump operation.
Signs It's Time to Replace
- Abnormal bearing noise: unusual noise during water-pump operation can indicate bearing deterioration
- Excessive play: abnormal radial or axial movement can indicate wear or deterioration of the bearing or associated components
- Rough rotation: resistance, roughness, or irregularity during rotation should be investigated
- Vibration: abnormal water-pump vibration can be associated with deterioration of rotating or supporting components
- Visible damage or corrosion: physical damage, corrosion, or deterioration identified during inspection should be assessed for serviceability
- Water-pump operating concerns: abnormal pump operation should prompt inspection of the impeller-end bearing and associated rotating components
Apex focuses on EMD engine components and water-pump system parts for EMD applications. The Ball Bearing — Water Pump, Impeller-End is identified by the specific EMD Part No. 908415 and DLW Part No. 16150405, allowing customers to source the component using established EMD and DLW references. Its precise identification as the impeller-end water-pump bearing helps distinguish it from the separate drive-gear-end bearing, EMD 908410 / DLW 16150417.
