ation has a positive effect on the bearing operating life. FAG’s newly designed housing seal meets these challenging requirements. This has been verified in numerous test runs under harsh conditions with extreme impacts of water. Triple ring bearings Triple ring bearings are ideal for the highperformance roll on the drive side of conventional anti-deflection rolls. The rotating center ring is guided by the Rolling bearing coatings Coatings are applied on rolling bearings or components to improve the run-in behavior and dry-running characteristics or to optimize wear and friction behavior. Bearings subject to high loads and stresses in paper machines are coated with a tungsten carbide/carbon layer (Triondur®). This layer is characterized by high hardness and a low friction coefficient. Wear resistance increases, and as a result of the low friction coefficient, adhesive wear in particular is minimized. This offers significant benefits for mixed friction or problems resulting from slip stress. If particularly effective corrosion protection is a priority, Corrotect® electroplated cathodic rust protection is used. On heavily loaded bearings, PTFE coatings on the external circumference of the outer ring ensure good sliding behavior with a very low friction coefficient. This means that bearings coated with this material can be used effectively as nonlocating bearings, thereby minimizing the axial displacement forces caused by friction. Bearing housings Together with FAG bearings, our housings form extremely reliable functional units. The dimensions correspond to current shaft diameters and bearing sizes of the 1.. series for drying cylinders in paper machines. Manufacturers are constantly striving to provide even longer availability for new paper machines with higher speeds and increased efficiency. Since the quality of raw materials is often poor, the dryer fabric must always be kept clean. This also increases requirements for the housing seal design. Reliable seal operspecially designed barrel or cylindrical rollers on both sides. The selection and combination of these rollers are based on the specific requirements. Brass cages are designed in a way that enables them to support the rolling elements securely and ensure optimum oil supply.
