SKF's Scotseal PlusXL contains four internal sealing lips designed to keep road contaminants out and bearings lubricated. The seal’s inside diameter provides wider contact with the shaft than ordinary wheel seals, virtually eliminating misalignment or cocking during installation. What’s more, the Scotseal PlusXL offers broad compatibility with all popular synthetic fluid lubricants. Manufactured of Hydrogenated Nitrile Butadiene Rubber (HNBR), the Scotseal PlusXL is engineered to withstand excessive heat (up to 300 degrees F) from frequent braking and the extreme cold conditions. The PlusXL also incorporates a patented Waveseal design that continually sweeps oil back to the bearings.
