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.

Solution to Noise
Rotary bearing noise common with dust and scarred two solutions as below:
(1) the dust acoustic control method of rotary with dust and other foreign bodies, the cyclical vibration happens, the so-called dust, the size of its vibration and noise, and with or without. Dust acoustic control methods: improve the rotary bearing/wheel bearings cleaning method, before installation to bearing, shaft and hole and all parts to match the strict cleaning clean; Remove the foreign body in lubricant; To improve the bearing seal; Avoid the use of material is not pure plastic cage or foreign bodies are embedded.
(2) the scars of sound control method of rotary bearing rolling surface crack, indentation, or rust, if any, will occur like rivet rivet cyclical vibration and noise, the cycle may be fixed but mostly, the corresponding relationship between speed into a scar on the channel occurred in a row, scars on the ball, and the noise with the installation and lubrication condition and have certain changes. This kind of noise control methods: installation not knock when the bearings, bearing and shaft assembly after a load bearing seat when prevent bearing oblique; Inventory to prevent rusting bearing and transport to prevent impact vibration; Using high viscosity of grease.
(3) the lubrication factors cause the noise and its countermeasures of lubricant selection error and lack of lubricant degradation and induration, can lead to rotary bearing/wheel bearing vibration and noise, and the noise without certain regularity. In this case, only to choose suitable lubricant, adjust its lubrication dose, prolong the service life of lubricant and reasonable replacement cycle.
(4) with the host about the noise and its countermeasures of this kind of noise is not a simple caused by bearing, thus single to find reasons from the aspects of bearing is invalid, dealing with host comprehensive attention, when it is necessary to improve the performance of the host. The main narrative in the motor common hum and rack resonant sound.
A. the hum of the motor and its countermeasures: the motor shaft axial vibration will cause A lot of high frequency noise, hum, its frequency and axial vibration frequency is the same, can is A constant change. Hum way to prevent and prevent axial vibration method is the same.
B. bracket resonant sound and its countermeasures: the outer ring quality is inherent vibration caused by axial bearing frame axial bending vibration mode, then called resonant acoustic noise. Increase the preload method can improve the quality of outer ring of the axial natural frequency, resonance condition, reduce the noise.
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.
lewing ring bearing is a new type of slewing product, usually called slewing ring, which is usually composed of worm, slewing ring, other components. Since the core components are slewing bearings, they can simultaneously withstand axial forces, radial forces, and overturning moments. Compared with traditional rotary products, the new rotary drive features easy installation, easy maintenance and a greater degree of installation space.
Slewing bearing are widely used in construction applications including truck cranes, manlifts, turntables, port machinery, modular vehicles, small wind
Slewing bearing is one of our main products.
1. four point contact ball slewing bearing (no gear, external gear, internal gear);
2. two row ball slewing bearing;
3. crossed cylindrical roller slewing bearing;
4. three row cylindrical roller slewing bearing;
5. crossed tapered roller slewing bearing;
6. ball and roller combined slewing bearing.
With advanced  science and technology, the company develops and manufactures various kinds of  bearing products with inner diameter of over 100 mm according to the national standard,such as large-size and extra-large-size deep-groove ball bearings,angular contact ball bearings,single,double and four-row cylindrical roller bearings,spherical roller bearings,single,double and four-row tapered roller bearings,spherical ball bearings,thrust ball bearings,thrust  roller bearings,slewing bearings,and split bearings,the products are widely used in the fields all over the country, such as port,machine tools,mining,metallurgy,power industry,medical,heavy machinery,coal machinery,cement machinery,petroleum exploration as well as national defence industry.With the right to handle the export.
