The Multiquip 55005-03 is a genuine OEM Rear Ball Bearing designed for Multiquip concrete vibrators, including the CV1A, CV2A, CV2B, CV3A, and CV3B series. As a factory-sourced component, this bearing meets the original design tolerances specified for these vibrator models, ensuring it seats and performs exactly as the original part did. Sourced directly through Multiquip's OEM supply chain, the 55005-03 is the correct replacement when addressing rear bearing wear or failure on compatible vibrator units. DHS Equipment stocks this part to help you get your equipment back in service without guesswork.
Key Features
- OEM Precision Tolerancing — Manufactured to the exact dimensional and load-rating specifications of the original bearing, ensuring correct press fit and rotational performance inside the vibrator housing.
- Drop-In Rear Position Replacement — Engineered to seat directly into the rear bearing position of compatible CV-series vibrators without reworking the housing or shaft.
- Broad CV-Series Compatibility — Confirmed fitment across the CV1A, CV2A, CV2B, CV3A, and CV3B Multiquip concrete vibrators, covering multiple head sizes within the lineup.
- Sustained Vibration Output — A correctly functioning rear ball bearing keeps the eccentric shaft spinning true, maintaining consistent vibration frequency and amplitude for effective concrete consolidation.
- Genuine OEM Sourcing — Part number 55005-03 is a factory Multiquip component, not a generic substitute, so material grade and geometry match the original specification without compromise.
The rear ball bearing in a concrete vibrator supports and stabilizes the rotating eccentric shaft at the back of the vibrator head assembly. As the shaft spins at high speed, the bearing absorbs both radial and axial loads generated by the eccentric motion, allowing smooth, consistent rotation that translates into effective vibration energy delivered into the concrete. When the rear ball bearing wears or fails, the shaft loses stability, vibration output becomes irregular or drops off entirely, and continued operation can cause accelerated damage to the surrounding housing and shaft components.
