Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the precise thickness and bore specification required by Multiquip for correct stack-up and component clearance in the C30 pump drivetrain.
- Drop-In Fitment for C30 Series Pumps — Engineered specifically for cycloidal-drive Mayco concrete pump models; seats correctly without shimming or machining.
- Broad C30 Series Coverage — Compatible with C30HD, C30HDNI, C30HDNI Precision, C30HDN, C30HDNI Zenith, C30HDG, C30HDZ, and C30HDGA variants.
- Protects Adjacent Components — A correctly sized spacer maintains proper load distribution across shaft and bearing surfaces, preventing accelerated wear on surrounding drivetrain parts.
- Sourced from Multiquip's Authorized Parts Network — Supplied as a genuine OEM replacement, ensuring the part you receive matches the original production specification.
A spacer is a precisely dimensioned component used to establish and maintain correct axial or radial clearance between mating parts within a mechanical assembly. In a cycloidal concrete pump like the C30 series, spacers position rotating and stationary components at the correct distance from one another, ensuring that loads are transferred evenly and that bearings, seals, and drive elements operate within their designed range of motion. When a spacer is worn, deformed, or incorrectly sized, it can cause misalignment, uneven bearing loading, and accelerated wear throughout the surrounding assembly — making an exact-specification replacement essential during any rebuild or repair.
