The Multiquip 335419100 Intermediate Ball Bearing #6304 is a genuine OEM component designed for MQD2H, MQD2HA, MQD3H, and MQD3HA diaphragm pumps. Sourced directly from Multiquip, this bearing meets the exact tolerancing and dimensional specifications required for proper pump operation. If you're servicing a Multiquip diaphragm pump in this series, 335419100 is the correct OEM-specified bearing for this position in the drivetrain. DHS Equipment stocks genuine Multiquip parts so you can get your equipment back in service without compromise.
Key Features
- OEM-Grade Bearing Tolerancing — Manufactured to the exact radial clearance and load rating of the original #6304 specification, ensuring smooth rotation and correct shaft alignment within the pump assembly.
- Drop-In Installation — Dimensioned at 20x52x15mm to seat directly into the intermediate bearing position with no modification to the housing or shaft required.
- Confirmed Fitment for MQD Diaphragm Pumps — Compatible with MQD2H, MQD2HA, MQD3H, and MQD3HA models, covering both standard and variant configurations in the Multiquip diaphragm pump lineup.
- Sustained Pump Output — A correctly fitted intermediate bearing keeps the eccentric shaft running true, maintaining consistent diaphragm stroke and full rated flow output across the pump's operating range.
- Genuine Multiquip OEM Part — Carries the Multiquip OEM part number 335419100, so you can order with confidence that this is the manufacturer-specified component for this bearing position.
The intermediate ball bearing in a diaphragm pump supports the eccentric shaft that drives the pumping diaphragm back and forth to move fluid. It carries both radial and axial loads generated during operation, keeping the rotating assembly centered and reducing friction at the bearing journal. When this bearing wears or fails, the shaft loses support, which leads to increased vibration, accelerated diaphragm wear, and eventual loss of prime or pumping capacity.
