ZD 150×180×16/30 Rectangular Double Spring Combined Skeleton Oil Seal Extended Life Wheel Reducer Hub Seal For CG30B ZL30B-II CLG830 LG833 XG930 Replacement

Formulated for loader wheel reducer applications where maximizing mean time between seal replacements directly impacts fleet profitability, this ZD series 150×180×16/30 double spring combined skeleton oil seal incorporates advanced FKM fluororubber compound technology for significantly extended service life compared to standard NBR seals. The premium FKM lip material maintains its elasticity, oil resistance and sealing force through prolonged exposure to hot gear oil, EP (extreme pressure) additives and thermal cycling that rapidly degrades conventional rubber compounds. Dual corrosion-resistant stainless steel tension springs provide consistent radial force without spring fatigue or rust degradation, ensuring sustained sealing performance across extended oil drain intervals. The reinforced rectangular cross-section with integrated metal skeleton resists compression set and permanent deformation even after thousands of operating hours under heavy load. For loader fleet operators implementing condition-based maintenance programs and seeking to reduce seal-related wheel-end service events, this long-life seal delivers measurable reduction in total cost of ownership through fewer replacements, less downtime and lower labor costs.
