Hardness Gradient Geared Slewing Bearing
Progressive hardening is the ultimate solution to gear tooth failure problems. This process is widely applied to slewing bearing used on the excavator, crane, and the drilling rig.
1. The progressive hardening technology revolutionizes the way gear teeth are produced, which greatly extends service life of the slewing ring
2. Over 2000 such sets have been sold out with no failure occurring in operation since records began.
3. Available with a 3-year quality warranty.

Elliptical Raceway Slewing Bearing
The world’s first of its kind single-row ball, elliptical raceway slewing ring bearing is a great improvement over the traditional double-row ball, circular profile raceway configuration.
There are many benefits to the use of elliptical raceway slewing bearing, including
1. Over 30% increase in load bearing capacity. Doubled lifetime compared to one with the same diameter raceway and ball configurations.
2. More than 20% raw material savings, which translates into over 10% cost savings.
3. Compared to a three row ball slewing ring, the single-row ball, elliptical raceway configuration costs 35% less.
Widely used in XCMG, Fuwa, Hitachi, Liugong, Zoomlion, Lishide, Carter, Jonyang,Rongan, etc., to replace the three row roller slewing bearing.

Levelness-Adjustable Slewing Bearing
Adjusting the levelness of the slewing bearing is critical to minimize tilting moment loads, most notably, when the slewing ring is to be installed on a ladder truck. This self-leveling slewing bearing comes with a leveling instrument that facilitates the adjustment of levelness.

  • Single Row Ball Slewing RingThe single row four point contact ball slewing ring consists of two rings. It has tightened mechanical structure and low weight. Its rolling element is a row of steel balls which connect the elliptic raceway with four points. Therefore, our single row ball slewing ring can bear axial, radial and turnover moment simultaneously...
  • Cross Roller Slewing RingThe cross section of the raceway is linear type. The roller of the slewing ring is column type and each two adjacent rollers are cross arranging. Therefore, half of the rollers bear the upward axial force and the rest bear the down forward force. The column type roller features linear contact with raceway and little fraction coefficient...
