The Multiquip CM20721 Brush Holder 110V is a genuine OEM component designed for the CX40A concrete pump. As a direct Multiquip OEM part, it is manufactured to the exact specifications required for proper electrical contact and motor performance. This part is confirmed to fit CX40A series equipment, making it a straightforward service replacement when the existing holder shows wear or damage.
Key Features
- Correct Voltage Rating — Rated at 110V to match the electrical specification of the CX40A motor, ensuring proper brush contact pressure and current transfer.
- Genuine OEM Construction — Manufactured by Multiquip to the same tolerances as the original, maintaining consistent brush seating and stable motor commutation.
- Direct-Fit Replacement — Dimensioned to seat into the motor housing exactly as the original, with no reworking of mounting points or terminals required.
- Confirmed CX40A Fitment — Verified for compatibility with the CX40A cycloidal-driven concrete pump series.
- Protects Motor Longevity — A worn or damaged brush holder causes uneven brush wear, arcing, and motor overheating; replacing it restores stable commutation and extends motor service life.
- Electrical Safety Compliance — Using the correctly rated OEM holder ensures the motor circuit operates within its designed electrical parameters, reducing risk of overload or arcing faults.
The brush holder secures and guides the carbon brushes that maintain continuous electrical contact with the motor's commutator or slip ring. It keeps the brushes aligned at the correct angle and pressure so that current flows smoothly to drive the motor. When a brush holder cracks, deforms, or loses its tension, brushes wear unevenly or lose contact entirely, leading to arcing, reduced motor output, and eventual motor failure — making timely replacement critical to keeping the concrete pump running at full capacity.
