Outer spherical stainless steel bearing manufacturing manufacturers a large number of inventory and manufacturing capacity

Linear bearing is a linear motion system, used for linear travel and cylindrical shaft. Because the bearing ball is in contact with the bearing jacket, the steel ball rolls with the least friction resistance, so the linear bearing has small friction and is relatively stable. It does not change with the bearing speed, and can obtain the smooth linear motion of high sensitivity and high precision. Linear bearing consumption also has its limitations, the most important is that the impact load capacity of the bearing is poor, and the bearing capacity is also poor, followed by linear bearing vibration and noise at high speed movement. Automatic selection of linear bearings is included. Linear bearings are widely used in precision machine tools, textile machinery, food packaging machinery, printing machinery and other industrial machinery sliding parts.

The outer spherical ball bearing is actually a variant of the deep groove ball bearing. It is characterized by the spherical outer diameter surface of the outer ring, which can be matched into the corresponding concave spherical bearing seat to play the role of aligning. The outer spherical bearing is mainly used to bear radial and axial combined loads, which are mainly radial loads. It is not suitable to bear axial loads alone.

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.

Deep groove ball bearing (GB/T 276-2003) formerly known as single row centripetal ball bearing, is the most widely used kind of rolling bearing. It is characterized by small friction resistance, high speed, can be used to bear radial load or radial and axial simultaneous action of the combined load on the machine parts, can also be used to bear axial load on the machine parts, such as small power motor, car and tractor gearbox, machine tool gearbox, general machines, tools and so on.

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.
