Structural characteristics,performance,and application scope

The single-row four point contact ball type slewing bearing is composed of two socket sleeves and is compact in structure and light in weight .Due to its steel balls contact with circular rollingtrack on four points,it can bear axialforce ,radial force and overturning moment at the same time,and it can be selected for use in engineering machinerysuch as rotary conveyer,welding operation machine,medium and small-scale hoists,and excavator.
