UTOT Three-row roller slewing bearing has three seat-rings,which separate the upper,lower and radial races,via which the load of each row of the rollers may be specified.It may bear different loads simultaneously and its load capacity is the largest one among the four models. Thanks to the large size of its axle and radius,it is sturdy and especially suitable for hearvy-duty machines which require large working radius.such as bucket-wheel excavators,wheeled cranes,ship cranes,ladle turret,heavyduty mobile cranes etc.

Three-row cylindrical roller combined slewing ring (13 series) size range:

Diameter size range: 300mm ~ 5000mm

Diameter size range: 500mm ~ 6500mm

Width range: 50mm ~ 300mm

Slewing bearing applications

1. Wind generator

Tower and yaw bearings are installed in the junction of tower and the cockpit; pitch bearings are installed in each blade root and hub joints. Each wind turbine equipment use three sets pitch bearings and a set of yaw bearing. pitch bearing ring material select 42CrMo, treatment with the overall quenching, raceway select surface-hardening.

2. Marine Crane

In general, marine crane use double-row different diameter ball, four-point contact ball, three-row roller inner gear structure slewing bearings.

3. Offshore crane

According to different requirement for carrying capacity, offshore crane usually use four-point contact ball slewing bearing and three-row roller inner gear slewing bearing.

4. Port mobile crane

Port cranes usually use internal or external gear, 4 meters in diameter three rows roller slewing bearings to withstand high overturning moment. 

5. stacker-reclaimer

Slewing bearing stacker-reclaimer usually use is ball column combined type, three-row roller and cross-roller, the majority diameter over 3 meters. Due to poor working conditions, dusty, these bearings have high load capacity, long life and good sealing performance feature.

6. Ferris wheel

Usually use four-point contact ball slewing bearing, diameter 4100mm, thickness 85mm. 

7. Ship unloaders

Usually use three rows of outer roller tooth structure, about 4 meters in diameter 

8. Tower crane

Usually use small size four-point contact ball bearings or double-row ball, diameter not more than 2 meters

9. Radar antenna

Usually use three-row roller slewing bearing, slow rotation

10. Shield

Diameter from 2.5 meters to 6 meters, some larger diameter, these bearings work in very poor conditions, bearing a large load, corrosion resistance, short life.

11. Ladle turret in steel plant

Usually these bearing are three-row roller slewing bearings, because work in the dust and high temperature conditions, so s have high demands for maintain, grease and seal.

12. Engineering machinery

Usually use small size four-point contact ball bearings or double-row ball, diameter not more than 2 meters
