    MiningLubricants for extreme stresses

    Scrollen
    Surface mining at full powerWithstand extreme stresses

    The very good wear and corrosion protection as well as the excellent mechanical stability BECHEM lubricating greases offer, enable reliable control over high specific loads. The influences of dust and moisture are significantly reduced, even with extended relubrication intervals.  

     

    The use of newly developed high-performance additives and their physical/chemical reactions with metal surfaces enables a further reduction in the friction value and wear to be achieved with greases from the BECHEM High-Lub FA series. For example, the use of BECHEM High-Lub FA 50 lubricating grease has proven to significantly extend the service life of slewing gear bearings in hydraulic excavators. Some lubricating greases have special solid lubricant combinations for use in bearings with very high contact pressures and/or shock loads. These characteristics are shared by the Berulit GA series, which has proven itself in practice worldwide when used in open gear drives, such as for ball, tube, and SAG mills as well as for slewing gears on excavators.

    An optimum hydraulic fluid is critical in mining.
    Reliable in all surface mining operationsWorldwide and in every climate

    At high external temperatures, oil temperatures in gear boxes can rise to values at which the oil ages much more quickly. But, in regions with very cold winters, the low temperature behavior of lubricants is even more important.

     

    These climatic conditions place great demands on the lubricating behavior of greases as well as their conveying behavior. The behavior at low temperatures is often the acid test for lubricating greases in belt conveyors and large equipment, such as excavators, dump trucks, and large bucket wheel excavators.

    Beruplex CF 2, BECHEM High-Lub L 2 MO, and BECHEM High-Lub LM 2 EP offer not only excellent wear and corrosion protection, but also feature outstanding pumping characteristics in the sometimes very long lines of central lubrication systems. BECHEM High-Lub LM 0 EP or BECHEM High-Lub LM 00 EPW can be used at extremely low temperatures of -40°C.

    Reliable, cost-effective lubrication under tough conditions requires not only the use of high-performance lubricants, but also experience in correct application. BECHEM specialists have the necessary expertise as well as, with the BECHEM rheometer curve, the necessary know-how to individually advise users and assess the conveying behavior of lubricating greases in central lubrication systems.
