Spherical roller bearings withstand harsh heavy duty environments

Ideal for heavy duty, harsh operating environments and where there is a need to compensate for shaft misalignment, Schaeffler Group's range of X-life E1 spherical roller bearings offer longer operating life, improved machine performance and higher reliability in harsh operating environments. The E1 range – which has now been expanded to include eight bearing series with bore diameters from 20mm up to 1,220mm – is suitable for a wide range of applications, including continuous casting machines used in steel processing, paper mills, wind turbine rotor shafts, and vibrating screens. The bearings are suitable for harsh operating environments, particularly in applications where very high load carrying capacities and reliability are key design criteria. Due to their robust design and high load carrying capacity, E1 spherical roller bearings in Schaeffler's premium quality X-life rating offer optimum solutions for vibrating screens. The low friction characteristics of the X-life E1 bearings not only withstands the very high alternating loads that occur in vibrating screens, but also help to reduce noise levels and operating temperatures, resulting in improved machine efficiency. In the larger-sized bearings with bore diameters greater than 320mm, the X-life E1 bearings benefit from having hardened sheet steel cages, which enable longer operating life due to significantly reduced wear. X-life Explained Spherical roller bearings are double-row, self-contained units that comprise solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings have cylindrical or tapered bores. Many bearing sizes within the E1 spherical roller bearing range can now be converted to X-life quality. These bearings have no central rib on the inner ring and are therefore able to use longer barrel rollers. Furthermore, the bearings benefit from improved kinematics, optimised surfaces and are made from higher performance materials. As a result, the basic dynamic load rating and basic rating life (under similar operating conditions) are improved significantly. This means that in certain applications, a smaller bearing solution can be provided. For the customer, these benefits translate into higher machine availability, new design possibilities, more economical bearing solutions due to downsizing; and lower operating costs due to reduced energy consumption.
