Structure:
Crossed roller bearings are a special type of bearings where the inner ring is split and the outer ring rotates.? Slewing bearing is also called rotary bearing, some people also call it:rotary bearing, slewing bearing. Slewing drive usually consists of worm gear, slewing bearing, shell, motor and other components.
Installation:
Crossed roller bearings are easy to operate when installing crossed roller rings because the divided inner or outer rings are fixed together with the crossed roller rings after the rollers and spacer keepers are loaded to prevent them from separating from each other.
Slewing bearing bearings correctly placed roller and isolation block. Put the selected cylindrical talker and round isolation block along the road, in the placement of adjacent cylindrical roller ten, its axis is perpendicular to each other, between two rollers separated by an isolation block.
3. Characteristics:
Crossed roller bearings can bear loads in all directions with only 1 set of crossed roller collar because the rollers are arranged in a cross pattern, and the rigidity is improved by 3~4 times compared with the traditional models.
Slewing bearing can bear axial force, radial force and tilting moment at the same time because the core part adopts slewing bearing.
4. Application scope:
Crossed roller bearings are mainly used in: machine tools with precision rotary indexing table, vertical and horizontal boring machine, vertical grinding machine, rotary surface grinding machine, large hobbing machine, gun and radar rotary table, large radio and optical telescopes, rotary camera, steering pivot and continuous casting machine, height-restricted pivot microscope table, pole center pivot, rotary steering rack, Welding brackets, rotary assembly fixtures, industrial robots, precision rotary tables, medical instruments, measuring instruments, IC manufacturing devices.
Slewing bearing bearings are mainly used in a wide range of applications: automobile cranes, railroad cranes, harbor cranes, marine cranes, metallurgical cranes, container cranes, excavators, filling machines, as well as CT machines, standing wave therapy instrument, navigation instruments, radar antennae, missile launchers, tanks, robots, and rotating restaurants and so on.
