Chicago Rawhide CR-16180 Oil Seal

The Chicago Rawhide CR-16180 oil seal is a compact, solid, single-lip rotary shaft seal engineered for dependable oil retention in gearboxes, transmissions, motors, pumps, and related equipment. It features a 1.625 in shaft bore (ID), a 2.441 in external diameter (OD), and a 0.313 in overall width, all housed in a steel case with a CRW1 design and a nitrile rubber (NBR) wave lip. A garter spring provides constant lip tension to sustain a reliable seal under load, while the wave-lip profile reduces friction and heat to improve efficiency. This seal is compatible with both oil and grease lubricants and is intended for press-fit housing installation. Operating temperature ranges from -40 °F to 210 °F, and it tolerates up to 10 psi of seal face pressure, making it suitable for moderate-pressure sealing in rotating assemblies. The part is cataloged as CR-16180 and is associated with the SKF Chicago Rawhide line of CR seals, reflecting its pedigree as a rugged, general-purpose seal for a variety of rotating applications such as gear reducers, motors, pumps, and wheel-end assemblies, where precise sizing (1.625 x 2.441 x 0.313) and a single-wave lip are critical for maintaining fluid containment and machine reliability.
