An aligning roller bearing is a bearing with a drum roller assembled between an inner ring with two raceways and an outer ring with spherical raceways. Aligning roller bearings have two rows of rollers, mainly bearing radial loads, but also can withstand axial loads in either direction. It has high radial load capacity, especially suitable for heavy loads or vibration loads, but cannot withstand pure axial loads. This kind of bearing outer ring raceway is spherical shape, so its aligning performance is good, can compensate for the coaxial error. Main applications: paper making machinery, reducer, railway vehicle axle, rolling mill gear box bearing seat, rolling mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer, vertical aligning bearing with seat.

The main features of stainless steel outer spherical bearings 1. The outer spherical bearing with seat can work under the condition that the two bearing seats are not coaxial, and the maximum automatic adjustment Angle can reach 2°. 2. Outer spherical bearing with seat has good rotation accuracy; It can be easily re-lubricated. The clearance is larger than that of the same size deep groove ball bearings, so the temperature difference has little influence on its accuracy. 3. The inner diameter of the outer spherical bearing with seat adopts "+" tolerance to form a clearance match with the shaft. The bearing is fixed on the shaft through the top wire, eccentric sleeve or tight sleeve on the upper side of the inner ring, which reduces the accuracy requirements of the shaft and makes it very convenient to install or replace the bearing. 4. Outer spherical bearing with seat is composed of outer spherical bearing and bearing seat. In use, there is no need to design the bearing box, small size, simple structure, can be directly bolted on the design part of the main engine, easy to use. 5. The outer spherical bearing with seat is generally pre-filled with grease and adopts the form of double or three lip seal. It is suitable for use in the occasions with more dust, mud and water and corrosive media, which is conducive to the work of the main engine. 6. Bearing seat as a whole structure, bearing capacity is large, good rigidity, bearing and bearing seat can be exchanged, that is, the same bearing seat can be installed with various types of bearings; Similarly, the same bearing can be matched with various types of bearing seats.

Angular contact ball precision bearings Precision machine tool bearingAngular contact ball bearings can bear radial and axial loads at the same time, and can also bear pure axial loads. Their axial load capacity is determined by the contact Angle and increases with the increase of the contact Angle. Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, additional axial force will be caused, and corresponding reverse load must be applied. Therefore, this kind of bearings are generally used in pairs. Double row angular contact ball bearings can bear large radial and axial bidirectional combined loads and torque loads mainly radial loads. It can limit the two-way axial displacement of shaft or housing, and the contact Angle is 30 degrees. Angular contact ball bearings installed in pairs can bear radial and axial combined loads mainly in radial direction, and can also bear pure radial loads. The series configuration can only withstand axial loads in a single direction, while the other two configurations can withstand axial loads in either direction. This type of bearing is usually selected and combined by the manufacturer and submitted to the user in pairs. After installation, the preload interference is preloaded, and the ferrule and steel ball are in the axial preload state, thus improving the stiffness and rotation accuracy of the whole set of bearings as a single support.

Deep groove ball bearing has simple structure and easy to use. It is a kind of bearing with the largest production volume and the widest application range. Widely used in automobile, home appliances, machine tools, motor, water pump, agricultural machinery, textile machinery and many other fields.

Spherical bearings are preferred for applications requiring simple equipment and parts, such as agricultural machinery, transportation systems or construction machinery.
