The Multiquip 1042620 Lower Ball Bearing is a genuine OEM component designed for ST6125D and ST4125D clean water submersible pumps. This is a direct OEM replacement sourced from Multiquip, ensuring the bearing meets the original dimensional and load-rating specifications required for these units. Verified fitment covers the ST6125D and ST4125D models, so you can order with confidence knowing this is the correct lower bearing for your pump.
Key Features
- OEM Bearing Specification — Manufactured to the original #6308/#7308 bearing specification, delivering the correct bore diameter, outer race dimensions, and load capacity required for these submersible pump applications.
- Drop-In Lower Bearing Position — Seats directly into the lower bearing housing of compatible ST-series submersible pumps with no rework or shimming needed to achieve proper shaft alignment.
- Confirmed ST-Series Fitment — Designed specifically for the ST6125D and ST4125D clean water submersible pump models.
- Protects Pump Shaft Integrity — A properly functioning lower bearing keeps the impeller shaft running true, preventing shaft wobble, seal wear, and premature motor failure that result from a worn or failed bearing.
- Genuine Multiquip OEM Part — Supplied as an authentic Multiquip replacement under part number 1042620, matching the original component installed at the factory.
The lower ball bearing supports the pump shaft at its base, absorbing both radial and axial loads generated during operation. It keeps the rotating shaft centered within the pump housing, which is critical for maintaining impeller clearance, protecting the mechanical seal, and ensuring smooth, efficient water transfer. When this bearing wears or fails, shaft runout increases rapidly — leading to seal leaks, elevated motor current draw, and eventual pump failure if left unaddressed.
