RKS.21.0741 L shaped slewing bearing with external gear
Advantage:RKS.21.0741 L-shaped slewing bearing with external gear, it features compact in design, light in weight, high precision and small fitting clearance. As the rollers are 1:1cross arranged, it is suitable for high precision mounting and capable to bear axial force, resultant moment and considerable large radial force. The four point contact slewing bearing find widely application for transporting, engineering machines as well as for military products.Technical parameters: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.We are a professional manufacturer of precision bearings, which has combine research,production and marketing together,Taking the advantage of the strong industrial basis , under the guidance of the pioneer in bearing industry. we grow up rapidly.After years of research and production practice,we have developed an very integrated system ,Now,we have solid technical strength,excellent processing facilities ,perfected Production & Test condition,and also completed quality control.

Features | Slewing bearing is also called:Slewing ring bearing /Turnable bearing/Slewing ring etc. Slewing Ring Bearings can accommodate axial, radial and moment loads acting single or in combination and in any direction. They are not mounted in a housing or on a shaft, but directly to a seating surface. The inner and outer ring are supplied with mounting holes. Both rings may have integral gears. They are also referred to as slewing rings and tabletop bearings. Slewing ring bearing can perform oscillating (slewing) as well as rotating movements. They may be used without gears or with internal or external gear | |
