Single Row Four Point Contact Ball Slewing Bearing

Slewing bearing also known as slewing ring bearing,turntable bearing.It contain outer ring,

inner ring,rolling body,seals.The material of our products are generally high alloy-structural 

steels ,such as 42CrMo 50Mn.The slewing bearing can work normally at a temperature of

 -30℃ to +70℃,and we can design special type as customer need.

The slewing bearing is a large-sized bearing with low speed and heavy load operation. Usually, the inner ring or the outer ring is toothed. It is used to connect two large parts that need relative rotation. The slewing bearing is widely used in engineering machinery, wind power equipment, port machinery and other fields. In recent years, due to the country's strong investment in infrastructure, new energy equipment and other fields, the market demand for slewing bearings has also increased sharply, and there is often a shortage of supply. On the other hand, there are many domestic slewing bearing manufacturers, especially in Xuzhou,To stand out, minimizing costs under the premise of ensuring product quality is the key to the company's emergence in the fierce market competition.
