Multiquip 040406309 Bearing 6309 C-3 BNLM 110B - OEM Replacement Part

This bearing supports the eccentric shaft assembly within the vibration case of the MVC-90H plate compactor, enabling the high-frequency vibrations that generate the machine's 3,350 lbs. centrifugal force at 5,600 vpm. The 6309 C-3 bearing features C-3 internal clearance for thermal expansion during operation and specialized sealing to protect against the dust, moisture, and debris encountered during soil and asphalt compaction work.

The MVC-90H's vibration system relies on this bearing to maintain smooth eccentric weight rotation at high speeds, which produces the low-amplitude, high-frequency vibrations essential for compacting granular soils. Bearing failure typically manifests as weakened or lost vibration during normal operation, excessive noise from the vibration case, or reduced forward travel speed from the normal 82 ft/min specification. Regular inspection of this bearing is critical for maintaining the compactor's maximum compaction area of 8,036 sq.ft/hr and preventing damage to the eccentric assembly and gears housed within the vibration case.
