Multiquip 047920090 Roller Bearing NJ307MC4 - OEM Replacement Part

This roller bearing (NJ307MC4) supports the rotary driven shaft in the eccentric assembly of Multiquip plate compactors, transferring engine power to the base plate while handling high radial and axial loads during operation. Two bearings are required per machine and work in conjunction with the eccentric rotators to convert rotational motion into the compaction force.

Located on the rotary driven shaft assembly, this roller bearing is a critical wear component that ensures smooth operation and prevents excessive vibration or shaft misalignment. The NJ307MC4 specification indicates a C4 internal clearance rating designed for the thermal expansion and operational loads specific to vibratory compaction equipment. When this bearing fails, symptoms typically include unusual noise, excessive vibration, reduced compaction efficiency, or shaft binding.

This bearing installs alongside part number 0403-06907 (bearing 6907C3) and works with the eccentric rotator assembly secured by socket head bolts. Regular inspection of bearing condition during routine maintenance can prevent catastrophic shaft failure and costly downtime.
