Product features: slewing bearing for excavator Slewing Ring Identification
Identifying slewing rings can sometimes be hampered by part worn serial/part numbers or OEM only references. In order to help identify your slewing ring, we recommend the following:
1. Provide the machine model on which the bearing fits.
2.Provide a quick drawing giving with the following dimensions noted as accurately as possible.
2.1-Inner ring and outer ring diameters
2.2-Inner and outer flange diameters and heights
2.3-The height of the inner ring, outer ring and total assembled height
2.4The PCD of mounting holes in the inner and outer rings. Also note hole size, through or blind and or taped
2.5-Gear detail including number of teeth, approx tooth pitch, tooth height and depth + profile if possible.

Method of extending the bearing's lifetime:
1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.
2. Don't allow strong impact, such as hammer striking, transfer roller pressure
3. Use the accurate installation tool, avoid to use cloth kind and short fibers
4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer
5. General inspection, such as the surrounding temperature, vibrate, noise inspection
6. Keep bearing cleaning from dirt, dust, pollutant, moisture.
7. Bearing should not be ultra cooled.
- Three rows of combined roller slewing bearing
Three row roller slewing bearing has three seat and radial raceway separate from top to bottom, to make each row roller load can be exactly determined, can carry a variety of load at the same time, is that the four kinds of products in one of the biggest bearing capacity, axial and radial size larger firm structure, especially suitable for the requirements of large diameter heavy machinery, such as bucket wheel excavators, wheeled cranes, deck cranes, ladle rotation, and a large tonnage crane machinery, etc.- Double row angular contact ball slewing ring bearing
Slewing bearing has three seat double, steel ball and isolation block can be directly discharged into rolling up and down, according to the stress state, arranged up and down two different diameter of steel ball. This open assembly is very convenient, and arc raceway of bearing Angle is 90 °, can bear a large axial force and overturning moment. When the axial force of the radial force is greater than 0.1 times the race must be specially designed. Slewing bearing pairs of axial and radial size is larger, solid structure, especially suitable for the requirements above medium diameter of tower crane, truck crane loading and unloading machinery, etc.- Single row cross roller slewing bearing
Single row cross roller slewing bearing, is composed of two seat, compact structure, light weight, high accuracy of manufacture, assembly, small gap of installation accuracy requirement is high, the roller of 1:1 cross arranged, can bear larger axial force and radial force and overturning moment. Is widely used in hoisting, transportation, engineering machinery and military products.
- Single row four-point contact ball slewing ring bearing
Single row four-point contact ball bearing slewing bearing is composed of two seat, compact structure, light weight, rolls four point contact ball and circular arc, can withstand the axial force and radial force and overturning moment. Rotary conveyor, welding manipulator, small and medium-sized crane and excavators and other construction machinery are optional.
