Sourced directly from Multiquip, this part meets the exact tolerances and specifications required for proper operation of the MQC-100 cycloidal-driven concrete pump. If you're tracking down the correct inner bearing for your MQC-100, part number A64190074 is the verified OEM replacement to spec.
Key Features
- OEM-Grade Precision Tolerancing — Manufactured to the exact dimensional and hardness specifications of the original bearing, ensuring correct load distribution within the pump drive assembly.
- Direct-Fit Replacement — Engineered to seat and align exactly as the factory original, slotting into the MQC-100 bearing housing without reworking or shimming.
- Confirmed MQC-100 Fitment — Verified for the MQC-100 concrete pump series; cross-reference part number A64190074 before ordering to confirm your specific unit.
- Sustained Drive Performance — A correctly seated inner bearing keeps the cycloidal drive rotating smoothly under load, maintaining consistent concrete output and preventing premature wear on surrounding drivetrain components.
- Genuine Multiquip OEM Part — Supplied through authorized Multiquip distribution channels, so you receive the same component installed at the factory — not an approximation.
The inner bearing in a cycloidal-driven concrete pump supports the rotating eccentric shaft assembly at the core of the drive mechanism, carrying both radial and axial loads generated during pumping cycles. It works in close coordination with the outer bearing to keep the drive shaft centered and rotating true under the considerable stress of moving concrete. When this bearing wears or fails, the result is increased vibration, accelerated wear on adjoining components, and ultimately a loss of pumping efficiency or a complete drive failure — making timely replacement critical to keeping the pump productive.
