If you have any inquiry about our products. the high-efficiency slewing bearing(yaw bearing) used in all the rotating part of industrial equipments. As for our production capability, we are capable of producing a rnage of min. 250mm~max. Dia 8,000mm (internal, external and gearless). Also the grade of accuray reaches din 4 class(agma14). Our slewing bearings are used in many different applications, for both military and civil use [for example in cranes on offshore platforms, truck cranes, tower cranes and so on.

Slewing bearings can accommodate axial, radial and moment loads acting singly or in combination and in any direction. They are not mounted in a housing or on a shaft, but directly to a seating surface. The inner and outer rings are supplied with mounting holes. Both rings may have integral gears. They are also referred to as slewing rings and tabletop bearings. Slewing ring bearings can perform oscillating (slewing) as well as rotating movements. They may be used without gears or with internal or external gears. It is Single Row Ball Type. Gear is located with the inner side of ring. Gear is divided in two types; one is high frequency induction hardened gear and the other is quenching & tempered. The pitch circle diameter 2,000 or more is mostly made by quenching and tempering heat treatment process.
