SKF SNL housing seals are the first line of defence against contaminants. Four-lip seals replace the previous double-lip seals. Four-lip seals are more efficient than double-lip seals and have a reduced coefficient of friction, allowing shafts to operate at higher speeds. In heavily contaminated environments, SKF recommends a three-barrier solution. This cost-effective sealing solution can have a significant impact on bearing service life, as it provides three barriers to contaminants.
