Rear Wheel Hub Oil Seal 6513712 For Heavy-Duty Truck FKM High Temperature Resistant Axle Shaft Seal Replacement Parts For Cargo Truck Axle Hub Bearing Waterproof And Anti-Leak Assembly

FKM Rubber Sealing Body Resists High Temperature And Grease Corrosion：High-performance FKM material avoids swelling and hardening under persistent contact with hot hub grease during full-load continuous truck operation, featuring outstanding anti-aging property for extended service cycle.

Full Enclosed Internal Metal Skeleton Prevents Seal Distortion And Displacement：Stamped metal inner liner boosts structural rigidity, resisting squeeze deformation under assembly load and eliminating oil leakage caused by seal offset or detachment from bumpy truck road vibration.

Spiral Self-Tightening Spring & Multi-Layer Oil Grooves Achieve Long-Term Zero Leakage：Circular spring maintains constant compression force against axle shafts, while multiple annular grooves store lubricant to sustain tight sealing without grease seepage under temperature alternation and heavy truck vibration.

Widened Outer Dust Lip Blocks Mud And Grit From Damaging Wheel Bearings：Extended integrated outer dust barrier repels rainwater, gravel and road debris away from bearing chambers, preventing bearing rust, abnormal noise and lock-up failure.

Universal Standard Dimension 6513712 Supports Direct Plug-And-Play Fit For All Heavy Cargo Truck Rear Axles：Standard size complies with general industry matching specs, enabling direct replacement during truck rear hub bearing overhaul without secondary modification to cut vehicle maintenance downtime.
