Even for tough operating conditions like a mining quarry, construction site, mine or some other harsh environment, there are now stronger bearings, and some of them are inside vibrating machines. Some equipment can vibrate during operation, which is considered a side effect, but many machines, such as vibrating sieves, are actually built on the principle of this vibration and the bearings inside them must withstand it. Through the use of state-of-the-art technologies in materials, lubrication, seals and design, NSK has developed a spherical roller bearing for machines with intense vibration, which has twice the life of conventional bearings and also withstands higher loads. With these products, industrial plants can now benefit not only from savings in bearing replacement costs, but also from lower maintenance costs and reduced equipment downtime through extended service intervals. The knowledge and experience gained from NSK's technology centers have been successfully and effectively used in the development of special bearings for heavy-duty applications. Sophisticated calculation, design and analysis methods, state-of-the-art manufacturing technologies, as well as rigorous tests and tests have contributed to these bearings achieving high performance and long service life. The bearings are equipped with high-precision, machined, one-piece brass cages with specially contoured roller pockets. Compared to conventional bearings, the surface roughness of the rollers and raceways of the inner and outer rings has been significantly improved, resulting in reduced roller slippage. The rollers have also been specially heat treated to prevent vibration and shock cracking. The curvature factor of the raceways and spherical rollers has been optimized to reduce misalignment and eliminate increased stresses in the contact area between the rollers and raceway surfaces. All of these improvements have reduced the risk of raceway damage due to surface fatigue over the life of the bearing. The improved design of spherical roller bearings for vibrating sieves also helps to stabilize load distribution within the bearing, bearing radial internal clearance and dimensional tolerances. Radial internal clearance is set to the second third of ISO bearing standards and tolerances for outside and bore diameters are half these ISO standards. With the need for continuous operation of machines 24 hours a day, 6,000 hours a year, the failure of even one component of the machine can have a significant impact on the operation and productivity of the entire mining complex and on the development of quarries. NSK's new long-life spherical roller bearings for vibrating machines are a milestone in reducing equipment downtime, lowering operating costs and increasing productivity. NSK bearings are available in twenty-two sizes, with outer diameters from 90 to 400 mm and bore diameters from 40 to 190 mm.
