ZD 150×180×16/30 Rectangular Double Spring Combined Skeleton Oil Seal Heavy-Load Anti-Leakage Wheel Reducer Seal For CG30B ZL30B-II CLG830 Loader Replacement

Built for 3-ton wheel loaders operating under sustained heavy-load conditions in mining, quarrying and large-scale earthmoving projects, this ZD series 150×180×16/30 double spring combined skeleton oil seal delivers uncompromising anti-leakage performance for wheel reducer hubs. The rectangular cross-section structure with rigid metal skeleton reinforcement maintains dimensional stability under extreme radial loads and chassis articulation, preventing the seal from ovalization or extrusion that leads to gear oil loss. Dual independently-calibrated tension springs provide automatic wear compensation as the sealing lip beds in, maintaining consistent contact pressure throughout the seal service life. For fleet managers and independent service shops battling chronic wheel-end oil leaks that lead to premature bearing failure and unscheduled downtime, this seal provides the heavy-duty sealing reliability demanded by production-critical loader operations.
