Turntable bearings are widely used in real industry and are called "machine joints". They are mainly used in truck cranes, railway cranes, port cranes, marine cranes, metallurgical cranes, container cranes, excavators, filling machines, and CT machine standing wave treatment equipment, navigation equipment, radar antenna base, missile launchers, tanks, robots and rotating restaurants.
Split cylindrical roller bearings are mainly used on crankshafts and in areas where bearings are difficult to reach. All integral cylindrical roller bearings in the maintenance and replacement is very difficult and equipment can not stop, split cylindrical roller bearings can show its special advantages, steel tube cold rolling mill crankshaft, ratchet, excavator, rolling mill drive shaft and large ventilation equipment is its main application areas. WYZZ has successfully developed split cylindrical roller bearings that can be installed anytime and anywhere to meet the needs of transmission conveyor roller bearings in the continuous casting cooling zone.
This type of bearing is a separable bearing, which can bear a large two-way axial load, but cannot limit the radial displacement of the shaft. This type of bearing and other types of axial positioning bearings (single, double row angular contact ball bearings, deep groove ball bearings, large cone angle double row tapered roller bearings), in the same journal, under the same axial load, the bearing width is the narrowest, bearing diameter minimum. This type of bearing has a lower limit speed.
This type of bearing roller is spherical type, because the seat raceway is spherical, with self-aligning performance. The axial load capacity is particularly large, and it can bear a number of radial loads while bearing axial loads. Oil lubrication is generally used when used. This type of bearing is mainly used for hydraulic generators, vertical generators, propeller shaft for ships, tower cranes, extruders, etc.
Angular contact ball bearings are divided into a variety of structures, single row angular contact ball bearings can withstand radial load and single direction axial load, DB combination, DF combination, four-point contact, double row angular contact ball bearings can withstand radial load and two-way axial load. Angular contact ball bearings are suitable for high-speed and high-precision rotation. This type of bearing is mainly used for machine tool spindles, high-frequency motors, oil pumps, air compressors, printing machines, etc.
Sendjimir bearings are mostly used in multi-roll cold rolling mills, with outer ring wall thickness, which is an ideal support roller bearing for multi-roll cold rolling mills. Its advantages are simple geometry, high manufacturing accuracy and high radial load capacity. The structural form without ribs and retaining rings is not allowed to bear the axial load, which is borne by the adjusting shims or thrust bearings at both ends. Most of them are used in multi-roll mills for rolling stainless steel and silicon steel strips. In recent years, due to the development of multi-roll mills, general wide sheet mills are also used...
Split spherical roller bearings are mainly used in places where bearings are difficult to install, such as long drive shafts or crankshafts with multiple support points. Split bearings provide the best solution when it is used for integral bearings that are very difficult to maintain, especially when the cost of replacing bearings is very expensive or when equipment is not allowed to stop for maintenance.
