114.28.800 series slewing ring with internal tooth used for high precision Air defense system with missiles and radar antenna

The slewing bearing is a special component that integrates rotation and transmission, reduces structural space and reduces equipment weight. In particular, radar turntables and armored rescue vehicle turntables require high-precision, low-noise, high-impact load, and stable rotation turntable equipment, all of which require dedicated rotation support.

The single-row cross roller swivel ring also consists of two inner and outer rings with a compact structure, high manufacturing precision, low weight and little assembly clearance. The inner ring and the outer ring are connected by rollers, the rollers are arranged in a 1: 1 cross, which can simultaneously absorb axial force, tilting moment and larger radial force.

Note

n1 is the nos of lubricating holes.Oil cup M10×1JB/T7940.1~JB/T7940.2.The Oil nipple’s location can be change according to the user’s application.
2. n-φcan change to tapped hole,the diameter of tapped hole is M,depth is 2M.
3. The tangential tooth force in the form is the max tooth force,the nominal tangential tooth force is 1/2 of the max one.
4. “K” is addendum reduction coefficient.
LONGWEI Transmission Slewing Bearing Co.,Ltd. is a slewing bearing manufacturer specializing in standard and non-standard slewing bearing.Over the years, we supplied high quality product & good service to every user and gain good credit.We have strict quality control system in our own factory,meanwhile, we have passed ISO9001-2008

Our slew bearing 113 series are single-row cross roller slewing bearings with teeth on the inner ring, you can use a pinion with it to bring the slewing ring rotary.The following table is the specification for different models:

Technical parameters required for slewing bearing selection as below:
1).Slewing bearing load (Includes axial load, radial load and tilting moment)
2). Percentage of each load and its occupation time
3). Speed or number of revolutions of the slewing bearing under each load
4).Circumferential force acting on the gear
5).Dimensions of the slewing bearing
6). Other operating conditions

The material, compressive property, abrasive resistance and hardness of balls will affect the load condition and service life of slewing bearing. Longwei slewing bearing Co., Ltd purchase balls from suppliers with high quality, and we will conduct test for the compressive property, abrasive resistance and hardness to eurens the quality of balls will meet the requirement.

We supplied high quality product & good service to every end user and valued distributors all over the world. We’ve enjoyed a very good reputation up to now.

Our manufacturing standard is according to machinery standard JB/T2300-2011, we also has been found the efficient Quality Management Systems(QMS) of ISO 9001:2015 and GB/T19001-2008. We devote ourselves to the R &D of customized slewing bearing with high precision,special purpose and requirements and has acquired certificate of China Classification Society .
