SKF 51108 shaft seal

The SKF shaft seal 51108 is a precision-engineered component designed to seal rotating shafts against housings. It protects bearings and sealing surfaces from the leakage of lubricants such as oil and grease, as well as from the ingress of dust, water, and other contaminants. This radial shaft seal consists of a metallic outer casing that ensures secure attachment and stable sealing against the housing. The primary sealing lip, often made of elastomer, is equipped with a spring spiral to maintain a constant contact pressure on the rotating shaft, thereby achieving effective sealing throughout its service life. A secondary sealing lip can provide additional protection against contaminants. The SKF 51108 is widely used in various industries, including mechanical engineering, the automotive industry, and plant engineering, where it contributes to extending the service life of machine components. These seals are essential for maintaining operational safety and efficiency. Technical data: Material: steel and elastomer (type depending on application), standard dimensions according to ISO standards, temperature range and pressure resistance vary depending on design.
