Multiquip 041006307 Bearing 6307ZZE C3 - OEM Replacement Part for Tamping Rammers

This sealed deep groove ball bearing provides critical support for the rotating crankshaft assembly in Multiquip tamping rammer gearboxes, handling the extreme impact forces generated during soil compaction operations. The 6307ZZE specification features double metal shields (ZZ) for superior contamination protection in dusty job sites, C3 internal clearance for thermal expansion under continuous operation, and BNM precision manufacturing for extended service life under the 600 blows-per-minute operating cycle of professional rammers.

During normal operation, rammer gearboxes use grease lubrication systems requiring maintenance every 8 hours with Shell Darina EP2 or equivalent high-temperature grease. Bearing failure symptoms include irregular striking amplitude, non-uniform foot action, excessive vibration in the handle assembly, or unusual noise from the gearbox housing. The MTR-60L and MTR-80L models generate impact forces up to 2,140 lbs per blow, making proper bearing function essential for reliable compaction performance in backfilling, embankment work, and pipeline trenching applications.

Compatible with the following Multiquip tamping rammer models:

• MTR-60L Tamping Rammer
• MTR-80L Tamping Rammer
