Widely used in tower cranes, large excavators, truck cranes, crawler cranes, port handling machinery, mining heavy equipment and other construction machinery.
• The hidden built-in gear design effectively prevents dust, water, sediment and impurities, with good wear resistance and corrosion resistance;
• Small radial dimension and compact layout save installation space, meeting the miniaturization design requirements of equipment;
• Internal meshing transmission runs smoothly with low noise and high operation stability;
• The drive mechanism is installed inside the bearing with narrow operating space, leading to difficult disassembly and maintenance.
Single-row four-point contact ball slewing bearing: 013 series and 014 series, e.g. 013.20.500, 014.25.710.
