Slewing bearing contains the outer ring, inner ring, rolling elements, seals, grease nipples, etc. Our
product materials are generally high alloy structures steel, such
as 42CrMo 50Mn. Slewing ring can work normally at a temperature of
50 ° C
-30 ° C to + 70 ° C, we can design special types according to
customer needs
