The Multiquip W166006LLU Bearing Ball SDP-2 is a genuine OEM ball bearing designed for STOW SDP-2 diaphragm pumps. Sourced directly from Multiquip, this bearing meets the original design specification for the SDP-2 and delivers the load capacity and dimensional accuracy the machine requires. Confirm your model against the SDP-2 fitment before ordering to ensure a correct, direct replacement.
Key Features
- Genuine OEM Tolerancing — Manufactured to the original dimensional and load-rating spec for the SDP-2, so bearing clearance and race geometry match the housing exactly as designed.
- Direct-Mount Replacement — Drops into the existing bearing seat on the SDP-2 without reworking the housing or adjacent components.
- SDP-2 Fitment — Confirmed for STOW SDP-2 diaphragm pump models; verify your unit against this fitment before purchasing.
- Sustained Pump Performance — A correctly seated ball bearing keeps the rotating assembly running true, maintaining consistent diaphragm stroke and rated flow output over the service life of the pump.
- Genuine Multiquip Part — Supplied under part number W166006LLU through authorized Multiquip distribution, ensuring you receive the correct component for the SDP-2 platform.
A ball bearing in a diaphragm pump supports the rotating shaft or eccentric drive that actuates the pumping diaphragm. It absorbs both radial and axial loads generated during operation, keeping the drive assembly aligned and rotating smoothly. When a bearing begins to wear or fails, increased vibration, noise, and shaft movement follow — leading to accelerated diaphragm wear and loss of pumping efficiency. Replacing a worn bearing promptly with the correct part restores proper shaft support and protects the surrounding components from secondary damage.
