SKF CRW1 R Radial Shaft Seal

SKF CRW1 R is a metal-cased radial shaft seal sized 115 mm ID, 140 mm OD, and 12 mm wide (115×140×12), designed for general industrial sealing tasks. The CRW1 R variant uses a nitrile rubber (NBR) lip with a garter spring to maintain lip contact with the rotating shaft, providing reliable exclusion of oil and ingress of contaminants in pumps, gearboxes, motors, and other equipment. The seal is part of SKF's CRW1 family, which is specified for general industrial applications and offered in multiple metric bore sizes; 115×140×12 is a common option within that line. The housing features a robust metal casing for structural rigidity, and some CRW1 variants employ a WAVE lip profile (CRW1 V) to improve pumping action and heat management; the R designation here denotes the standard lip variant. This 115×140×12 CRW1 R is commonly listed as a nitrile rubber rotary shaft seal suitable for petroleum-based oils and many hydraulic fluids within typical industrial service conditions.
