75x165x12.5/18.5 mm TC‑Type Flange Oil Seal, Double‑Lip Shaft Seal

This 75x165x12.5/18.5 mm TC‑type flange oil seal features reinforced metal flange shell for stable press‑fit mounting. Double‑lip design with garter spring maintains consistent radial pressure against rotating shaft.

It prevents lubricant leakage and blocks mud, splash‑water and dust ingress to protect bearings in heavy‑duty working conditions. Widely used for agricultural machinery, truck axle, transmission and engineering equipment. Suitable for auto‑parts wholesalers, repair shops and overseas bulk procurement.

Core functions

• Grease retention：Prevent lubricant leakage under heavy load
