The Multiquip 2029106 Ball Bearing is a genuine OEM component designed for MQ and STOW diaphragm pump models including MQ-D305, D306, MQ-D206H, MQ-D306HA, SDP-2, SDP-3, and CA90749. As a direct OEM replacement, this bearing is manufactured to the same tolerances and material specifications as the original part, ensuring consistent performance in demanding pump applications. Sourced directly through authorized Multiquip supply channels, the part is the correct part to specify when servicing any of the compatible diaphragm pump models listed above.
Key Features
- OEM-Grade Precision Tolerancing — Manufactured to exact dimensional and load-rating specs required for diaphragm pump shaft rotation, maintaining smooth, low-friction operation under continuous cycling loads.
- Drop-In Replacement — Matches the original bearing seat dimensions and shaft interface on compatible MQ and STOW diaphragm pumps, allowing straightforward installation without modification.
- Broad Diaphragm Pump Compatibility — Confirmed fitment across MQ-D305, D306, MQ-D206H, MQ-D306HA, SDP-2, SDP-3, and CA90749 diaphragm pump models.
- Sustained Pump Output — A properly functioning bearing keeps the pump's eccentric or drive shaft running true, preserving consistent diaphragm stroke and rated flow output. A worn bearing introduces shaft play that degrades pump performance and accelerates seal wear.
A ball bearing in a diaphragm pump supports the rotating drive shaft or eccentric assembly that converts motor power into the reciprocating motion of the diaphragm. By reducing rotational friction and maintaining precise shaft alignment, the bearing allows the pump to deliver its rated flow efficiently and consistently. When this bearing wears or fails, increased shaft runout places uneven stress on the diaphragm and surrounding seals, leading to reduced flow, fluid leaks, and potential pump failure if not addressed promptly.
