24 E&MJ; • JUNE 2014 www.e-mj.com COMPANY PROFILE-PAID ADVERTISEMENT When it comes to bearings, whether for mining or virtually any other industry, Schaeffler, together with our INA and FAG brands, has always been at the forefront of technological innovation. Industry firsts—such as the devel- opment of the needle roller & cage assembly or the groundbreaking ball grinding machine that is regarded as the foundation of the entire rolling bearing industry—have earned Schaeffler a unique distinction among the world's great bearing companies. With over 79,000 employees working in approximately 170 locations in 49 countries throughout the world, Schaeffler is one of the world's largest technology companies in family ownership. Our bearing solutions and expert service offerings are designed to improve the reliability and per- formance of mining equipment, while reducing downtime and overall operating costs. A Comprehensive Product Portfolio for Practically Every Application Rolling bearings are essential contributors to technological progress in the mining and pro- cessing industries. The very nature of the min- ing business requires extremely robust bear- ings, and Schaeffler products are specifically engineered to thrive in some of the harshest operating conditions on (or under) the earth. With a product portfolio comprised of 225,000 industrial products, Schaeffler offers one of the broadest product lineups in the bearing industry, complemented by innovative condition monitoring devices, mounting services as well as maintenance tools. Con- sequently, Schaeffler is able to offer a solution for virtually any application in the mining and processing industry. Following are a few snap- shots of how Schaeffler can make your mine more productive and more profitable: Schaeffler Solutions for Bucket Wheel Excavators FAG spherical roller bearings and spherical plain bearings are the ideal solution for the bucket wheel excavator's boom that has to support static loads as well as vibrations caused by the digging motion of the bucket wheel. For the bucket wheel shaft, FAG spherical roller bearings are able to handle high loads as well as compensate for shaft deflections and misalignments. Offering reduced downtimes and lower maintenance costs due to their flexible design, FAG split cylindrical roller bearings are the perfect solu- tion for the shaft inside the bucket wheel drive's transmission. Schaeffler Solutions for Tunnel Boring Machines At the heart of the tunnel boring machine lies the main bearing. Schaeffler's large axial- radial cylindrical roller bearings or tapered roller bearings in O-arrangement by FAG are ideally suited for this application. For bear- ings in the cutter wheels that are subjected to high shock loads, large differences in speeds and accelerations as well as high operating temperatures, Schaeffler offers its FAG tapered roller bearings made from case-hard- ened steel for extra-long service life. Schaeffler Solutions for Draglines and Shovels Schaeffler has some of the finest technical and economical solutions for virtually any bearing position in draglines and shovels, regardless of whether the application involves winding drums, pulleys, rope sheaves, rota- tion systems or transmissions. Spherical roller bearings, large matched tapered roller bear- ings and cylindrical roller bearings are popu- lar Schaeffler solutions for these positions. Schaeffler Solutions for Mining Trucks Many impressive Schaeffler solutions are hidden in the huge wheels of haul trucks. These include not only extremely durable wheel bearings for front and rear axles, but also complete bearing solutions for engines and planetary gear drives that are integrated into the rear wheels. For electric motors, Schaeffler offers insulated deep-groove ball bearings and cylindrical roller bearings to prevent damage from electric current. These bearings have long relubrication intervals and easily handle severe temperature fluctua- tions in both wet and dry conditions. Schaeffler Solutions for Conveyors For the drive pulleys in conveyor systems, Schaeffler offers FAG spherical roller bearings in either solid or split designs. While both types are equally capable of withstanding high loads and compensating for misalign- ments and shaft deflections, FAG split spher- ical roller bearings are a particularly attractive alternative, because replacing these bearings involves significantly fewer steps and less time. Easy on, easy off means less downtime. And less downtime means more profits. Schaeffler also offers a large selection of housings (solid and split) for conveyor sys- tems, including our latest innovation: the remarkable SNS housing. Its unique design extends bearing life by as much as 50% while providing the best-possible sealing perform- ance against contamination—even in extreme ambient conditions. Schaeffler Solutions for Crushers Because crushing machines require bearings that can both handle extremely heavy loads as well as compensate for misaligned bearing seats and tilting due to shaft deflection, Schaeffler proudly offers the FAG E1 spheri- cal roller bearings in X-life TM quality as the main bearings in jaw crushers. Compared to standard bearings, X-life bearings from Schaeffler offer up to 70% longer service life for the same load—or the same service life at much higher loads. In addition, X-life bear- ings deliver high static reliability while mini- mizing the strain on the lubricant due to reduced friction and lower bearing tempera- tures. For our customers, this translates into extremely high machine efficiency and reduced operating costs. In addition, the abil- ity to downsize means more value for your bearing dollar . More Value • More Performance • More Reliability • More Durability • More Solutions. Only from Schaeffler. Forged from a History of Innovation and Industry Breakthroughs: The Right Solution for Every Bearing Position EMJ_pg04-45_EMJ_pg04-45 6/4/14 9:00 AM Page 24
