57.15x76.27x9.3/12.7 mm NBR Radial Shaft Oil Seal, Oil‑Resistant Wear‑Resistant High‑Pressure Resistant

This 57.15x76.27x9.3/12.7 mm NBR radial shaft oil seal is built with metal reinforcement shell and garter spring, designed as high‑performance sealing component for automotive applications.

It seals rotating shafts effectively to stop lubricant oil leakage, meanwhile blocks dust, mud and splash moisture entering mechanical assemblies. It protects bearings and related transmission parts and lowers premature failure risk under medium‑pressure working conditions.

High‑quality brand‑new aftermarket replacement part, strictly manufactured according to dimensional tolerance requirements. Suitable for auto repair workshops, auto‑parts wholesalers and overseas bulk procurement.

Core functions

• Oil retention：Prevent lubricant leakage and maintain stable internal lubrication environment
• Dust & contaminant exclusion: Keep dirt, mud and splash water out of equipment housing
• Reinforced metal shell: Maintain geometry and resist deformation during installation
• Garter spring pre‑load: Sustained pressing force against shaft surface for stable sealing under pressure

Features & Benefits

• Premium NBR nitrile rubber with metal reinforced shell, excellent oil‑resistant, wear‑resistant and medium high‑pressure resistant performance for automotive working conditions.

• Double‑lip plus garter‑spring pre‑load design, realizes oil retention and dust exclusion simultaneously.
