Four Point Contact Ball Bearing

Four-point contact ball bearings

Four-point contact ball slewing bearings can withstand torque loads, both the single row angular contact ball bearings and double row angular contact ball bearings features. Only four-point contact ball bearings in contact to ensure the formation of two normal work. It is generally applied to those of pure axial load or axial load large synthetic loads where contact was two, four point contact ball bearings high speed limit, but also for those high-speed operation of the occasion. Slewing Bearing / Slewing Ring Bearing      Slewing bearing is a kind of special structure of large bearings which can withstand large axial load, radial load and overturning moment, integrating supporting, rotation, transmission, fixed and other functions. Under normal circumstances, slewing bearings have their own mounting holes, lubricants and seals, which can meet various of host need  under different  working conditions; On the other hand, slewing bearings themselves are compact, easy to guide the rotation,easy installation and easy maintenance, so they widely used in material handling equipments, mining machines, construction machinery, port machinery, wind power generation, medical equipments, radar and missile launchers and other large rotating devices. According to different structure, slewing bearing can be divided into the following types:1, the four-point contact ball slewing bearing2, double row different diameter ball slewing bearing3, crossed cylindrical roller slewing bearings4, three-row cylindrical roller combined slewing bearing. 011.75.4000 Dimensions:4226*3772*174 material 50Mn/42CrMo/other

Four point contact ball slewing bearing

Single-row four point contact slewing bearing (01 series) 1.Description: The single-row four point contact ball slewing bearing is composed of 2 seat-rings. The balls contact with the circular race at four point,via which the axial force, radial force and resultant moment may be born simultaneously. 2. Packing 1 Bearing surface is covered with the anti-rust oil first; and then wrapped with the plastic film; 2 And then packed with kraft paper and professional belts; 3 At last, with wooden box totally at the outer packing to invoid the rust or the moist; 4 We can depend on the customers demand to be packed; 3. Features: Compact in structure and light in weight. 4. Application: slewing conveyers, welding arm and positioner, medium duty cranes, excavators and other engineering machines. Bearing surface is covered with the anti-rust oil first; and then wrapped with the plastic film; And then packed with kraft paper and professional belts; At last, with wooden box totally at the outer packing to invoid the rust or the moist; We can depend on the customers demand to be packed;

We can offer single-row ball slewing ring, dual-row ball slewing ring, single-row cross-roller slewing ring and tri-row roller slewing ring. And each kind of slewing ring has three types, non-gear, outer gear and inner gear. From small size(d=80mm) to large size(d=4000mm) slewing rings that we could make in our factory., standard or non-standard as per customers special requirement. Id depends on the type of the slewing bearing
