ZZ bearing is a specialized slewing bearing manufacturer based in China. Founded in 1998, we have been present in the slewing ring bearing markets at home and abroad for almost 30 years. Strong manufacturing capabilities and decades of experience and expertise enable us to earn a good reputation in the Chinese slew bearing industry. We design and produce various Slewing Bearing, available with thousands of standard specifications to choose from.
Three row roller slewing bearing can bear different loads simultaneously. The capacity load is the largest one comparing with other type slewing bearing. Due to the large axial and radial dimension & solid structure, it is especially suitable for heavy-duty machinery, such as harbor crane,ship crane, etc.
