The Multiquip 14311 Cam Bearing is a genuine OEM component designed for the C30HD series cycloidal-drive concrete pumps, including the C30HD, C30HDG, C30HDZ, C30HDGA, C30HDN, C30HDNI, and related Zenith and Precision fuel-injection variants. As a direct Multiquip OEM part, it meets the exact tolerancing and material specifications required to maintain pump output consistency and drivetrain integrity in demanding concrete placement applications. Sourced directly through authorized channels, this bearing is the correct replacement to specify when servicing any C30HD family machine. DHS Equipment stocks genuine Multiquip parts to help you get the right component the first time.
Key Features
- Precision Cam Bearing Tolerancing — Manufactured to OEM specification for the cycloidal drive system, ensuring correct load distribution across the cam profile and minimizing eccentric wear over service life.
- Drop-In Replacement for C30HD Series — Engineered to seat directly into the bearing housing of C30HD concrete pumps without rework or custom fitting, restoring the drivetrain to its original operating geometry.
- Broad C30HD Family Coverage — Confirmed fitment across C30HD, C30HDG, C30HDZ, C30HDGA, C30HDN, C30HDNI, C30HDNI Zenith, and C30HDNI Precision pump configurations.
- Sustained Pumping Pressure — A correctly functioning cam bearing maintains smooth cycloidal drive rotation, which directly supports consistent concrete output volume and pressure. A worn bearing causes erratic stroke delivery and accelerated internal wear.
- Genuine OEM Part — Carries the Multiquip OEM designation, confirming it is the same component used in original machine assembly — not a generic substitute.
The cam bearing supports the eccentric cam shaft within the cycloidal drive assembly of a concrete pump, allowing the cam to rotate smoothly under the high cyclical loads generated during pumping strokes. It acts as the critical interface between the rotating cam and the surrounding housing, absorbing radial forces and maintaining precise cam geometry so that each piston stroke delivers a consistent volume of concrete. When this bearing wears or fails, the cam loses its centered rotation path, leading to uneven piston travel, loss of output pressure, increased vibration, and accelerated damage to surrounding drivetrain components.
