The Multiquip 2063040 Ball Bearing is a genuine OEM component designed for MQ and STOW diaphragm pump series equipment. This is a direct OEM replacement sourced through Multiquip's authorized parts network, ensuring the correct specification for your pump. Compatible models include MQ-D206H, MQ-D306HA, MQ-D305, D306, SDP-2, SDP-3, and CA90749 diaphragm pumps. Ordering by part number 2063040 confirms you are receiving the exact bearing specified for these machines.
Key Features
- Genuine OEM Precision — Manufactured to the same tolerancing and load ratings as the original bearing, maintaining correct shaft alignment and rotational accuracy within the pump.
- Drop-In Installation — Matches the original bearing seat dimensions for a direct swap with no reworking of the housing or shaft required.
- Broad Diaphragm Pump Compatibility — Fits MQ-D206H, MQ-D306HA, MQ-D305, D306, SDP-2, SDP-3, and CA90749 models across the MQ and STOW diaphragm pump families.
- Sustained Pump Output — A correctly seated ball bearing keeps the drive mechanism running smoothly, supporting consistent flow rate and pressure delivery during extended pumping operations.
- Wear Protection — Resists premature fatigue under the cyclic loading conditions typical of diaphragm pump drives, extending service intervals between bearing replacements.
The ball bearing in a diaphragm pump supports the rotating drive shaft and eccentric mechanism that actuates the diaphragm back and forth to move fluid. It carries both radial and axial loads generated during each pumping cycle, allowing the drive components to spin freely with minimal friction. When this bearing wears or fails, it can cause increased vibration, noise, and shaft wobble that accelerates wear on surrounding components — and ultimately leads to a loss of pumping efficiency or complete drive failure.
