• Three-barrier solution

    Substantial cost savings in harsh environments

    For a Swedish mineral-processing facility, it meant savings of €23,232 over a two-year period.

    The three-barrier solution is ideal for conveyors operating in the mining and mineral processing industries. The solution comprises a sealed SKF SE housing filled with SKF grease and a sealed SKF Explorer spherical roller bearing. The housing and bearing seals as well as the grease in the housing’s cavity act as a three-fold barrier that protects the bearing against contaminants found in the mining and mineral processing industries. This increases the service life of the bearing by up to 300%.

    Third barrier: Seal on the SKF Explorer spherical roller bearing

    Second barrier: SKF LGEP 2 grease in the housing cavity

    First barrier: seal on the SKF SE housing
