Description
The SKF 11299 radial shaft seal is designed to provide reliable performance in demanding oil and grease sealing applications. Built with a robust metal case, it ensures a precise fit and added durability, while the SKF Bore Tite coating on the outside diameter fills minor housing imperfections to improve sealing efficiency.
At its core, the CRW1 design incorporates an SKF WAVE lip made from nitrile rubber (NBR). This advanced lip profile creates a higher pumping rate and reduces heat generation, minimizing wear and extending service life. A garter spring maintains consistent radial load on the shaft, ensuring optimal sealing under a wide range of operating conditions.
With a shaft diameter of 28.58 mm, housing bore of 50.37 mm, and seal width of 6.35 mm, the SKF 11299 supports speeds up to 3,720 r/min and circumferential speeds of 5.57 m/s. Offering low friction, reliable sealing, and excellent temperature resistance from –40 °C to +100 °C, it is ideal for industrial and automotive machinery requiring long-lasting performance.
