803400210 XCMG GR2605 motor grader lip seal

XCMG original factory rotary shaft lip seal ring, suitable for the transmission/hydraulic systems of graders/loaders, etc., prevents oil leakage, dustproof and wear-resistant, easy to install, and ensures stable shaft sealing.

Core Definition and Structure

Type: Rotary shaft lip seal ring (skeleton oil seal), with an inner/outer skeleton and a self-tightening spring. The sealing lip fits against the shaft surface, preventing lubricating oil leakage and impurity intrusion.

Structure: Composed of a sealing body, a reinforcing skeleton, and a self-tightening helical spring. The lip is precision-machined, resulting in a low coefficient of friction and reliable sealing.

Material: Nitrile rubber (NBR)/Fluororubber (FKM) optional, oil-resistant, heat-resistant, and aging-resistant, suitable for construction machinery operating conditions.
