The Multiquip EM20328TKIT Bearing Kit is a genuine OEM component designed for C30HD series concrete pumps, including the C30HDGA, C30HDZ, C30HDG, C30HDN, C30HDNI, and C30HD models. As a factory-authorized kit, it delivers the exact bearing specifications required to restore your pump to proper operating condition. This kit is stocked and sold by DHS Equipment, your authorized Multiquip parts source. Confirm your model code against the fitment list above before ordering to ensure a correct match.
Key Features
- Genuine OEM Bearing Tolerances — Manufactured to Multiquip's exact dimensional and load-rating specifications, ensuring the bearings seat and rotate correctly within the pump housing without premature wear.
- Complete Kit Format — Includes the full bearing set needed for the service interval, so you have everything on hand before teardown begins — no partial-order delays mid-repair.
- Broad C30HD Series Coverage — Fits C30HD, C30HDGA, C30HDZ, C30HDG, C30HDN, C30HDNI, and C30HDNI Zenith and Precision variants, consolidating one kit across multiple configurations.
- Restores Pump Shaft Stability — Worn bearings allow shaft deflection that causes accelerated seal failure and output pressure loss; a fresh kit eliminates play and brings stroke consistency back to spec.
- Direct OEM Replacement — Part number EM20328TKIT maps directly to the Multiquip bill of materials for the C30HD family, so the kit installs using standard service procedures without modification.
Bearings in a concrete pump support the rotating and reciprocating shafts that drive the pumping action, absorbing both radial and axial loads generated during continuous operation. When bearings wear, shaft movement increases, leading to uneven pressure output, accelerated wear on adjacent seals and housings, and eventually pump failure mid-pour. Replacing bearings as a complete kit — rather than individually — ensures all load-bearing surfaces are renewed at the same time, restoring smooth, consistent pump performance and extending the service life of surrounding components.
