Single Row Ball Slewing Bearing is with the same structure with four point contact ball type-the ball and raceway are 45° contact, due to it has good stability and high cost performance, it has been used widely in many equipment, like excavator, crane, aerial work platform. etc. our normal production is mainly for this type. we have optimized the design contact angle, raceway quenching depth and hardness of single row ball slewing bearing to make our slewing bearings have longer service life.
Single Row Ball Slewing Bearing Features and Benefits
The single row ball bearing and roller bearing slewing ring is mainly composed of inner, outer ring and steel balls. The steel ball plays a vital role in the use of the excavator slewing bearing. Therefore, the quality of the steel ball directly affects the service life of the slewing bearing. The steel balls we choose are provided by a manufacturer who specializing in the production of steel balls for many years. They have decades of experience in the production of precision bearing steel balls. As one of the best slewing ring suppliers, we have verified that their steel balls are reliable and durable. When the steel ball arrived our warehouse, we will strictly check the size and the hardness must reach HRC62-66. The steel ball material is Gcr15, and the precision grade of steel ball is usually divided into G40, G60, G100 according to different size.
