Axial cylindrical roller bearings according to DIN 722 (series 811 and 812) The versions 813, 814, 874, 893, and 894 are not standardied. Tolerances Running, design and dimension tolerances of axial cylindrical roller bearings are equivalent to the axial bearings standard tolerances, see section bearing data. Axial minimum load Axial cylindrical roller bearings have always to operate under axial load to avoid any slip between rollers and bearing washers. If external load is too small, you may use springs to achieve a pre-stress of the bearing.
Nowadays, bearings are one of the most commonly used machine parts because their rolling motion make almost all movements easier and they help reduce friction. Bearings have two key functions: They transfer motion, i.e. they support and guide components which turn relative to one another. They transmit forces. The main purpose of bearings is to prevent direct metal to metal contact between two elements that are in relative motion.
spherical roller thrust bearings apply to precise instrument, the electrical appliance of low noise, automobile, motorbike and other machines. It is used the most widely in mechanical industry. We can also supply various types of bearings according to your sample and design. Manufacturing high-grade products is our permanent goal.
