The Multiquip W166304 Ball Bearing SDP-2 is a genuine OEM component designed for SDP-2 STOW Diaphragm Pump equipment. As a direct OEM replacement, this bearing is manufactured to the exact tolerancing and load ratings required by the SDP-2 platform, ensuring a correct, consistent installation every time. Sourced directly through authorized Multiquip supply channels, W166304 is the part number specified for this application — so you can order with confidence knowing it will fit and perform as intended.
Key Features
- OEM-Grade Precision Tolerancing — Manufactured to the exact bore, outer diameter, and radial clearance specifications required for the SDP-2 diaphragm pump, ensuring proper load distribution and smooth rotation.
- Direct-Fit Replacement — Drops into the original bearing seat without modification, maintaining the correct shaft alignment and housing fit that the pump was engineered around.
- Confirmed SDP-2 Fitment — Verified for use on STOW SDP-2 Diaphragm Pump models; use part number W166304 to confirm compatibility before ordering.
- Smooth, Low-Friction Operation — A correctly seated bearing keeps rotating components turning freely and quietly; a worn or failed bearing causes vibration, heat buildup, and accelerated wear on surrounding pump components.
- Genuine Multiquip OEM Part — Supplied through authorized Multiquip distribution, this is not a substitute or approximation — it is the same part specified in the OEM service documentation for the SDP-2.
A ball bearing supports rotating shafts by reducing friction between moving surfaces through a series of precision-ground steel balls contained within inner and outer races. In a diaphragm pump like the SDP-2, bearings allow the drive components to rotate smoothly under load while maintaining correct shaft alignment. When a bearing wears out, it creates excess play in the shaft, leading to vibration, noise, increased heat, and eventually damage to the pump's internal components — making timely replacement critical to keeping the pump operating at full output.
