The Multiquip EM402434 Bearing Bushing is a genuine OEM component designed for Mayco concrete pump models C30HD, C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDG, and C30HDZ. Sourced directly from Multiquip, this bushing matches the original specification for a correct, confident installation. Verified fitment across the C30HD series makes EM402434 the straightforward choice when servicing these concrete pumps.
Key Features
- Genuine OEM Material Grade — Manufactured to the same dimensional and material tolerances as the original bushing, ensuring correct bearing surface contact and load distribution within the pump assembly.
- Direct-Fit Installation — Matches the original mounting bore and interface dimensions of the C30HD series, dropping into place without secondary machining or fitting.
- Broad C30HD Series Coverage — Confirmed fitment for C30HD, C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDG, and C30HDZ Mayco concrete pump models.
- Sustained Pump Operation — A properly seated bearing bushing maintains shaft alignment and reduces metal-to-metal wear; a worn bushing accelerates shaft and housing damage, leading to costlier repairs.
- Verified OEM Part Number — Order with confidence knowing EM402434 is the correct Multiquip part number for this application, eliminating guesswork at the parts counter.
A bearing bushing serves as a precision wear interface between a rotating or reciprocating shaft and its surrounding housing. By absorbing friction and maintaining correct shaft alignment, it protects both the shaft and the housing bore from accelerated wear during operation. In a concrete pump like the C30HD series, where the pumping mechanism operates under continuous load and vibration, a degraded or worn bushing can cause shaft play, increased vibration, and eventual damage to surrounding components — making timely replacement essential to keeping the pump delivering consistent output.
