Corteco - CO19034447B - Simering Ring 130x105x13 Claas 7700039131

This oil seal fits on the front axle of the host tractor. It prevents lubricant leakage from the axle housing and blocks dirt and moisture from entering the bearing cavity. The seal sits between the rotating shaft and the stationary housing, maintaining a fluid barrier under normal operating pressures. A worn or hardened seal allows oil to weep past the lip, which can lead to bearing starvation and eventual axle damage. The seal is manufactured by Corteco to match the original housing bore and shaft contact surface, so no additional shimming or adapter is needed during installation. Replace the seal whenever the axle hub is disassembled, and ensure the sealing lip faces the lubricant side.
