The Wacker Neuson Bearing is a genuine OEM component designed for PDT3A, PDI3A, PDI3A(I), PDT2A, and PDI2A(I) series diaphragm pumps. As a factory-sourced part, it is manufactured to the exact tolerances required by these pump models, ensuring correct load distribution and consistent rotational performance. This bearing is a direct replacement for worn or damaged units across the compatible PDT and PDI pump lines.
Key Features
- OEM Precision Tolerancing — Manufactured to the exact dimensional and load-rating specifications of the original, maintaining correct shaft alignment and minimizing internal play within the pump assembly.
- Direct Drop-In Replacement — Matches the original mounting configuration and bearing seat dimensions, so installation follows the standard service procedure without modification to surrounding components.
- Broad PDT and PDI Series Compatibility — Confirmed fitment across PDT3A, PDI3A, PDI3A(I), PDT2A, and PDI2A(I) diaphragm pump models, covering both standard and pump diaphragm variants.
- Sustained Pump Output — A correctly fitted bearing keeps the pump's internal drive components running true, supporting consistent diaphragm stroke and steady flow performance over extended run times.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this is the same bearing supplied in original equipment — backed by the manufacturer's part number 5100075514.
A bearing supports rotating or reciprocating components by reducing friction between moving parts and carrying radial or axial loads within the assembly. In a diaphragm pump, the bearing helps maintain precise alignment of the drive shaft or eccentric mechanism that actuates the diaphragm, directly influencing stroke consistency and pump output. When a bearing wears or fails, increased play in the drivetrain can cause uneven diaphragm movement, accelerated wear on surrounding components, and a noticeable drop in pumping efficiency.
