The Wacker Neuson Ball Bearing is a genuine OEM component designed for the PST2 400, PS2 500, PSA2 500, PSR1 500, PSG2 500, and PSTF2 400 series submersible pumps. As a direct manufacturer-sourced part, the meets the original engineering tolerances specified for these pumps, ensuring the bearing seats and loads correctly without adaptation. This genuine OEM Ball Bearing covers a wide range of voltage configurations across the PS and PST pump families, making it the correct choice for both 110 V and 230 V variants.
Key Features
- OEM-Specified Radial Load Tolerances — Manufactured to the exact dimensional and load-rating specs required by Wacker Neuson's submersible pump motor assemblies, not a generalized bearing substitute.
- Drop-In Shaft Fitment — Designed to seat directly onto the pump motor shaft with correct bore sizing and race geometry, matching the original installation without rework.
- Broad Series Compatibility — Confirmed fitment across PST2 400, PS2 500, PSA2 500, PSR1 500, PSG2 500, and PSTF2 400 submersible pump models, including 110 V and 230 V variants.
- Sustained Motor Shaft Support — A properly functioning ball bearing keeps the motor shaft centered and running true; a worn bearing introduces shaft wobble, accelerated seal wear, and eventual motor failure.
- Submersible Environment Rated — Selected for use inside a submerged pump housing where moisture ingress and continuous rotation demand consistent bearing integrity to protect the motor.
The ball bearing in a submersible pump supports the motor shaft radially, allowing it to spin freely while maintaining precise alignment between the rotor and stator. In a pump operating submerged and under continuous load, the bearing absorbs both radial forces from the impeller and any axial thrust generated during pumping. When a ball bearing begins to wear, increased friction raises motor operating temperature, shaft runout worsens, and mechanical seals are placed under uneven stress — ultimately leading to water ingress into the motor housing. Replacing the bearing at the first sign of noise or vibration protects the broader motor assembly and extends service life.
