The Multiquip W19TB188 Needle Bearing SDP-2 is a genuine OEM Needle Bearing designed for STOW SDP-2 diaphragm pumps. As a direct OEM replacement, this bearing is manufactured to the same specifications as the original component, ensuring correct fitment and dependable service life in your diaphragm pump. DHS Equipment supplies this part as an authorized Multiquip source, so you can order with confidence knowing you are receiving an authentic component. Confirm your model code against SDP-2 series equipment before ordering to ensure compatibility.
Key Features
- Genuine OEM Needle Bearing Construction — Manufactured to precise radial load tolerances specific to diaphragm pump drive assemblies, maintaining consistent rotational accuracy under continuous cycling.
- Direct OEM Replacement — Engineered to seat and retain exactly as the original, requiring no shimming or adaptation during installation on SDP-2 series pumps.
- SDP-2 Diaphragm Pump Fitment — Confirmed fitment for STOW SDP-2 diaphragm pump models; verify your model code prior to ordering.
- Sustained Drive Efficiency — A correctly functioning needle bearing keeps the pump drive shaft aligned and rotating freely; a worn bearing causes increased friction, shaft deflection, and accelerated diaphragm wear.
- Authorized Multiquip Source — Sourced directly through an authorized Multiquip distributor, this is the same genuine OEM component specified for the SDP-2 from the factory.
A needle bearing supports radial loads along a rotating shaft using slim, cylindrical rollers that allow high load capacity in a compact profile. In a diaphragm pump, the needle bearing supports the eccentric drive mechanism that converts rotational engine power into the reciprocating motion needed to flex the diaphragm and move fluid. When a needle bearing wears, it allows excessive shaft play that disrupts the diaphragm stroke, reduces pump output, and can lead to premature failure of surrounding drive components.
