Maintenance engineers, equipment rebuilders, and industrial DIYers working on large-bore rotating assemblies need metric NBR TC double-lip oil shaft seals that match exact bore dimensions without guesswork.\u003c\/p\u003e\n    \u003cp\u003eThese TC-type radial shaft seals feature a nitrile rubber (NBR) body bonded to a steel reinforcing case, with a primary sealing lip loaded by an internal garter spring and a secondary dust-exclusion lip. Available in 43 size variants spanning inner diameters from 200mm (≈7.87 in) to 400mm (≈15.75 in), outer diameters from 230mm to 440mm, and widths of 15mm, 16mm, 18mm, or 20mm — select the exact ID × OD × Width combination your application requires.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include agricultural gearbox output shafts, industrial conveyor drive housings, heavy-duty pump shaft assemblies, and construction equipment final-drive sealing — anywhere a large-bore rotating shaft passes through a stationary housing and must be sealed against oil, grease, and airborne particulates.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard metric bore housings.
