Multiquip EM14412 Bushing 1 1/4 CRS

The Multiquip EM14412 Bushing 1 1/4 CRS is a genuine OEM bushing designed for the C30HD series concrete pumps, including the C30HD, C30HDG, C30HDZ, C30HDGA, C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith. As a factory-authorized replacement component, it meets the exact material and dimensional requirements specified for these Mayco concrete pump models. Sourced directly from Multiquip, the part ensures a correct, drop-in fit without the guesswork of cross-referencing aftermarket alternatives. DHS Equipment stocks this part to keep your concrete pump running at full capacity.

Key Features

• Genuine OEM Material Grade — Cold-rolled steel (CRS) construction meets the hardness and wear-resistance specifications required for concrete pump bushing applications, where abrasion and load tolerance are critical.
• Exact Dimensional Fit — Machined to the 1 1/4-inch specification, this bushing seats correctly in the pump's bore without shimming or reworking the housing.
• Broad C30HD Series Coverage — Confirmed fitment across C30HD, C30HDG, C30HDZ, C30HDGA, C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith concrete pump models.
• Sustained Pump Output — A correctly sized bushing maintains shaft alignment and reduces play in the pump mechanism, preserving consistent concrete flow and output pressure across pours.
• Direct Multiquip OEM Sourcing — Supplied as a factory-authorized part under part number EM14412, eliminating substitution risk and ensuring traceability for fleet maintenance records.

A bushing in a concrete pump serves as a wear interface between rotating or reciprocating components and their housings, reducing metal-to-metal contact and absorbing the lateral loads generated during pumping cycles. In the C30HD series, this 1 1/4-inch cold-rolled steel bushing supports smooth mechanical movement and helps maintain the alignment tolerances the pump depends on for consistent output. When a bushing wears beyond its service limit, it allows excess play that accelerates wear on adjacent components, causes vibration, and can lead to seal failure or shaft damage if left uncorrected.
