SKF 12363 CRW1 R Oil Seal

SKF 12363 CRW1 R is a small-bore, single-lip radial shaft oil seal with a metal case and a nitrile lip featuring SKF’s Wave lip design for reduced friction and heat. It measures 1.25 in inside diameter, 1.752 in outside diameter, and 0.25 in cross-section width, and it includes a garter spring to maintain seal contact on rotating shafts. Marketed as a Gorman-Rupp replacement (cross-reference 25227-303), this seal is listed in SKF catalogs as 12363 CRW1 and is commonly sourced from SKF-authorized distributors and retailers under the CRW1 designation. The nitrile lip provides compatibility with mineral oils and common pump lubricants, making it a direct fit for small-bore pump and gear applications where a robust, durable seal is required.
