The slewing ring, also known as a turntable bearing or ring race, is a large bearing used primarily to support a load while permitting rotation about a sign axis. The key points about steel slewing ring: 1. Application, Used in cranes and excavators, wind turbines, construction equipemnt, military vechicles, large radar systems. 2. Types: Single raw ball slewing rings, double row ball slewing rings, Roller slewing rings, Toothed slewing rings. 3. Components: outer race, Inner race 4. High load-carring capacity, Smooth operation, Ability to handle multiple load types simultaneously, campact design compared to seperate bearings. 5. Regular lubrication, Inspection for wear or damage, Proper sealing to prevent contamination. Steel slewing rings are essential components in many heavy machinery and industrial application where precise rotational movement under heavy loads is required. Their robust construction and ability to handle complex load…
