Product Introduction
National‑cross reference skeleton oil seals are China‑manufactured radial shaft seals interchangeable with National series aftermarket parts. Produced by compression vulcanization, they adopt NBR nitrile rubber as primary material, with optional FKM, silicone and EPDM for diverse working conditions. Built with metal skeleton and garter spring, most models feature double‑lip TC construction. They provide stable pre‑tension on rotating shafts to retain lubricating oil inside and block dust, mud and moisture from outside. Outstanding performance includes wear‑resistance, oil‑resistance and anti‑aging, effectively reducing bearing failure and extending equipment service life. They match National reference part numbers for direct drop‑in replacement without modification. Widely used for automotive engines, gearboxes, axles, trucks, agricultural machinery and general‑industrial rotating‑shaft assemblies. Multiple cross‑reference sizes are in stock. Custom dimensions, material grades and OEM part‑number marking are supported according to drawings or samples.
