Product Description

Four-point Contact Ball Slewing Bearing Bearing has two raceways respectively on inner ring and outer ring and can stand radial force, axial force and tilting moment. Under pure axial load, each steel ball only contacts one raceway on inner ring and outer ring. When the external radial load exceeds certain volume, steel balls will contact four raceways simultaneously. Steel balls should try to contact with each raceway in order to prevent larger abrasion or damage. Therefore, this type slewing bearings are mainly applied to the occasion that the axial load is predominant and tilting moment is larger.
