Key Features

• Genuine OEM Precision: — Machined to exact dimensional tolerances required for proper bearing alignment and load distribution in Mayco concrete pump drivetrains.
• Direct-Fit Installation: — Engineered to seat correctly within the bearing assembly of C30HD series pumps, eliminating the need for shimming or reworking during installation.
• Broad C30HD Family Coverage: — Fits C30HD, C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDG, and C30HDZ models in a single part number.
• Drivetrain Integrity: — Maintains correct axial spacing between bearings, preventing premature bearing wear and shaft movement that can lead to pump output loss or mechanical damage.
• Verified Multiquip Part Number: — EM20347 is the authoritative OEM reference for this component, giving you confidence that you are ordering the exact part specified for your machine.

A bearing spacer maintains the correct axial distance between adjacent bearings on a rotating shaft. By holding bearings at the proper spacing, it prevents them from shifting under load, which keeps shaft alignment true and distributes rotational forces evenly across the drivetrain. When a bearing spacer is worn, cracked, or missing, bearings can migrate out of position, causing uneven loading, accelerated wear, overheating, and ultimately shaft or housing damage that turns a minor service into a costly repair.
