SKF NBR Seal, 65mm ID, 85mm OD, 8mm

The SKF Radial shaft seal with a metal case and wave lip is designed for sealing oil or grease between rotating and stationary machine components or parts in relative motion. The seal features a durable metal case, an wave elastomer lip that provides a higher pumping rate to reduce heat generation, and a garter spring to maintain optimal contact with the shaft. Many of these seals also include the Bore Tite coating on the outer diameter, which helps fill minor imperfections in the housing bore for improved sealing performance.
