4412826 SEAL HITACHI for ZX180LC-3/4JJ1T

Precision Fluid Containment and Contamination Exclusion – The Critical Barrier for Rotating and Reciprocating Components.
This genuine Hitachi seal safeguards rotating shafts, reciprocating rods, and stationary joints, preventing costly lubricant or hydraulic fluid loss while blocking dirt, water, and abrasive particles from entering critical housings. Available in configurations including oil seals (e.g., 4244691, 4259935), dust seals (e.g., 263G8-47251), and complete seal groups (e.g., YB00004264, 4631062), it preserves fluid levels, protects bearings and gears, and ensures consistent system performance under pressure.

Advanced Lip Geometry and Premium Elastomer Formulation – Optimized for Long-Term Sealing Performance.
Manufactured from high-grade elastomers such as NBR, FKM, polyacrylate, or silicone—each selected for its specific application—this seal features a precision-molded sealing lip with an integrated garter spring where applicable. This design ensures consistent radial pressure against the shaft, accommodating minor runout and thermal expansion. The rigid outer case guarantees a secure press-fit within the housing bore, delivering dependable sealing even under vibration, pressure spikes, and temperature extremes. For undercarriage applications, floating seals with ultra-flat metal faces resist abrasion from mud, gravel, and contaminants in final drives and swing gearboxes.
