SKF 124020 Metal Face Seal 14.75 Shaft 16.695 OD 1.875 W HDDF1 Design

SKF 124020 is a metal-face seal from SKF’s CR Seals HDDF family, designed as a Heavy Duty Dual Face (HDDF1) unit for severe-service, low-speed applications. It seals around a 14.750 in shaft and accommodates a 16.695 in outer diameter, with a width of 1.875 in. The design uses two identical metal seal rings that face each other on a shared interface to create the sealing contact, while the lips are formed from nitrile rubber (NBR) for dependable dynamic sealing against lubricants. Two identical metal faces sit face-to-face to form the seal interface, a hallmark of SKF’s metal face seals, with the CR Seals 124020 designation identifying this specific size and lip-material configuration. HDDF1 units are specified for use under severe service conditions at relatively low circumferential speeds, offering reliable leakage control in demanding equipment and industrial machinery where a robust dual-face shaft seal is required.
