Four-point contact ball bearings
Single row four point contact ball type slewing bearings (slewing support) consists of two seat rings, compact structure, light weight, steel ball and arc roller four point contact, can withstand the axial force, radial force and tipping moment. Rotary conveyor, welding operators, small and medium-sized cranes and excavators and other construction machinery can be selected.
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

[Features] Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. [Single row angular contact ball bearings] Single row angular contact ball bearings can accommodate axial loads acting in one direction only. A single row bearing is typically adjusted against a second bearing. The standard assortment of single row angular contact ball bearings comprises bearings in the 72 B(E) and 73 B(E) series. Some sizes in the 70 B series are also available. [Double row angular contact ball bearings] Double row angular contact ball bearings correspond in design to two single row angular contact ball bearings arranged back-to-back, but take up less axial space. They can accommodate radial loads as well as axial loads acting in both directions. They provide stiff bearing arrangements and are able to accommodate tilting moments. The standard assortment of double row angular contact ball bearings comprises bearings in the 32 A, 33 A and 33 D series. [Four point contact ball bearings] Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads acting in both directions. For a given axial load, a limited radial load can be supported. These bearings take up considerably less axial space than double row bearings.
