The Multiquip 040300608 Bearing 608/MC3 is a genuine OEM bearing designed for MGX-SERIES and UM-SERIES concrete vibrators. As a factory-sourced component, it meets the original tolerancing and load specifications Multiquip engineers built these machines around. This bearing is a direct-fit replacement confirmed for MGX-SERIES gas-engine vibrators and UM-SERIES handheld units, keeping your concrete consolidation equipment running at full capacity.
Key Features
- Precision OEM Tolerancing — Manufactured to the exact radial clearance class (MC3) specified for this application, ensuring correct preload and smooth rotation under vibration-induced loads.
- Direct-Fit Replacement — Matches the original bore, outer diameter, and width dimensions for a straightforward swap with no reworking of the housing or shaft.
- Confirmed Fitment — Compatible with MGX-SERIES gas-engine concrete vibrators and UM-SERIES handheld vibrators across the Multiquip lineup.
- Sustained Vibration Output — A correctly seated bearing maintains consistent eccentric shaft rotation, which is what drives effective concrete consolidation; a worn bearing causes erratic frequency and amplitude loss.
- Genuine OEM Sourcing — Supplied as an authorized Multiquip OEM component, so the part number, material grade, and heat treatment match what left the factory originally.
The Bearing 608/MC3 supports the rotating eccentric shaft inside the vibrator head or motor assembly. It carries the radial loads generated by the intentionally offset rotating mass that creates the high-frequency vibration used to consolidate fresh concrete. The MC3 radial clearance designation is specifically chosen for applications where operating temperatures rise during sustained use, preventing the bearing from binding as components expand. When this bearing wears or fails, vibration amplitude drops, frequency becomes inconsistent, and the motor or drive shaft can sustain damage from the resulting imbalance.
