Single Row Ball Slewing Bearing

1.Product Introduction: With a single-row steel ball bearing structure, it is suitable for medium and light-load slewing equipment, featuring high slewing flexibility, convenient installation and maintenance, and controllable cost.
2.Structure Type: It consists of an inner ring, an outer ring, a single row of high-precision steel balls, cages and seals. The inner and outer rings are equipped with a single arc raceway, with nitrile rubber sealing covers on both sides, and the outer ring has through mounting holes.
3.Size Range: Outer ring diameter: 150 - 1800mm, inner ring diameter: 120 - 1650mm, height: 12 - 60mm.
4.Material: Inner ring / outer ring: 50Mn, 42CrMo; rolling elements: GCr15 bearing steel, GCr15SiMn (optional for impact resistance); seals: nitrile rubber, fluororubber (optional for oil and high temperature resistance).
5.Application Fields: Small construction machinery (mini excavators), amusement equipment (merry-go-rounds), light logistics equipment (turntable conveyors).
6.Key Inspection Items: Steel ball clearance, position accuracy of mounting holes, no cracks on the appearance.
