The structure of slewing bearing: commonly used are single-row ball slewing bearing, double-row ball slewing bearing, single-row cross-roller slewing bearing, three-row roller slewing bearing, ball-roller hybrid slewing bearing and other different structures, slewing bearing rolling body is made of fully hardened carbon-chromium bearing steel GCr15 or GCr15SiMn steel. These slewing bearings are divided into gearless, external and internal gear structures according to whether they have teeth and the distribution of teeth. The slewing bearing rings are made of hardened steel on the outside.

Slewing bearings of different structures have different installation methods.
Installation of slewing bearing: Correctly place the inner ring and outer ring, first lay the outer ring flat on the workbench, put the lower half ring and try to make the outer ring raceway correspond to the inner ring raceway, correctly place the rollers and isolate piece. Place the optional cylindrical roller and spacer block along this track. When placing adjacent cylindrical rollers, their axes are perpendicular to each other, and the two rollers are separated by an spacer block. Special application occasions require the use of special ball or roller isolation blocks, such as copper, aluminum and other high temperature resistant isolation blocks, generally installed on the bearings on the horizontal axis or continuously tumbling generators and those with high requirements on positioning and reliability. The slewing bearing used in the occasion.
