Key Features
- OEM-Grade Bearing Tolerancing — Manufactured to the original #6302 bearing specification (15x42x13 mm), ensuring correct radial load capacity and rotational precision within the pump assembly.
- Drop-In Compatibility — Engineered to seat directly into the original bearing bore with no machining or modification to the housing.
- Broad Diaphragm Pump Fitment — Confirmed fit for MQD2H, MQD2HA, MQD3H, and MQD3HA Multiquip diaphragm pump models.
- Protects Drivetrain Integrity — A worn or failed idler bearing can cause shaft misalignment, increased vibration, and accelerated wear on surrounding components; replacing it promptly restores smooth, stable operation.
- Genuine OEM Assurance — Supplied as a genuine Multiquip OEM part, so the material grade, geometry, and load ratings match the original production specification exactly.
The idler ball bearing supports the rotating shaft within the diaphragm pump drivetrain, absorbing radial loads and allowing the shaft to spin smoothly with minimal friction. When this bearing begins to wear, operators typically notice increased vibration, abnormal noise, or heat buildup near the bearing housing — all signs that shaft support has been compromised. Replacing the 335419200 bearing restores proper shaft alignment and prevents the kind of secondary damage to seals, shafts, and housings that a failed bearing can cause if left unaddressed.
