1. Precision slewing bearing：There are two major types of precision slewing bearing which are four contacting point ball bearing and cylindrical roller bearing. They can bear heavy axial load、radial load and tilting moment. We adopt pre-loading designing method and make the clearance as small as possible even to 0. Therefore, our precision slewing bearing has the characters of high rigidity and high precision. Inner gear or outer gear types are available according to customer’s needs. The highest precision of our bearings can be up to P4. They are mainly applied in precision machine tools, medical equipment, turntable, radar, and all kinds of precision test equipment.
2. General slewing bearin：There are different types of general slewing bearing such as four contacting point ball , crossed roller, tri-row roller, double row with different diameter balls, double row with four contacting point ball, and combination of balls and rollers type etc. It can bear tilting moment and large combination loadings of axial & radial load. This bearing have mounting holes on both inner and outer ring. And the optional type with outer or inner gear are available. It’s very convenient to be installed and use. They are widely used in engineering machinery, harbor facilities, marine crane, mining equipment, trailer turntable, and various mechanical slewing unit. The max diameter of our bearing cam be over 6 meters.
