23940

23940, as a self-aligning roller bearing, its core function is to provide reliable support for mechanical equipment that needs to bear heavy loads and has axis alignment deviations. It features a two-row roller structure, with one common spherical raceway on the outer ring and two inclined raceways on the inner ring. It has the automatic self-aligning performance, which can compensate for coaxiality errors and is not affected by the angle deviation between the shaft and the bearing housing or the shaft's bending. At the same time, it can withstand large radial loads and axial loads in any direction. For example, the FAG brand model 23940-S-K-MB has a basic rated dynamic load of 550,000 Newtons and a static load of 1,080,000 Newtons, suitable for heavy or vibration load conditions. Some models (such as 23940 CC/W33) have supplementary lubrication structures and can be used in scenarios requiring continuous lubrication. They can operate under low friction and low temperature rise conditions and are compatible with various working conditions such as low-speed heavy load and high-speed light load. They have a standard size of inner diameter 200 millimeters, outer diameter 280 millimeters, and width 60 millimeters, suitable for the installation requirements of most equipment, and are easy to install and remove. They can also be installed or removed according to different shaft diameters using locking rings or disassembly rings, and are widely used in mining machinery, metallurgical equipment, large motors, reducers, and other fields, helping equipment operate stably and extend its service life.
