SKF CR27541 Oil Seal

SKF CR27541 is a small-bore, nitrile-lip oil seal from the CR family (Chicago Rawhide 27541) designed for rotating shafts in compact housings. It follows the CRWH1 small-bore radial shaft seal configuration and accepts a shaft bore of 2.75 inches (69.9 mm), an outer diameter of 4.008 inches (101.8 mm), and a cross-section thickness of 0.438 inches (11.1 mm). The lip is formed from nitrile elastomer, and the seal is commonly cataloged as SKF 27541 or CHR27541 across SKF and Chicago Rawhide distributor listings, reflecting cross-compatibility within the CR line. This part is suited to light- to medium-duty machinery and equipment where space constraints demand a compact yet reliable oil seal for rotating shafts, such as small motors, pumps, and gear-driven assemblies. In supplier catalogs you’ll see the 27541/CR27541 designation paired with multiple cross-reference numbers, underscoring its role as a standard replacement part in the 2-3/4 inch bore family.
