Stainless steel series spherical bearing with seat The bearing and bearing seat are made of high-quality 304 stainless steel, and the solid bearing seat is more solid and stable. After advanced technology production, the appearance of mirror treatment, no black spots and burrs, beautiful, and corrosion resistance, highlighting the noble grade of bearing with seat. 1. Good corrosion resistance. Ordinary stainless steel can not resist corrosion, it is easy to be corroded in an acid and alkali environment, and 304 stainless steel bearings can be used in a strong environment. 2, rust prevention. It never rusts, even in water. 3, no magnetic. Generally, stainless steel bearing magnetism is very large, and it can be sucked up with a magnet, while 304 will not.

What is stainless steel spherical bearing 1, stainless steel spherical bearing The stainless steel outer spherical bearing is actually a variant of the deep groove ball bearing, which is characterized by the spherical surface of the outer diameter of the outer ring, and 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 the radial and axial combined load based on the radial load, and it is generally not suitable to bear the axial load alone. 2. Classification of stainless steel outer spherical bearings Outer spherical ball bearing with vertical seat Outer spherical bearing with square seat Outer spherical ball bearing with diamond seat Outer spherical ball bearing with convex round seat Outer spherical ball bearing with ring seat Outer spherical ball bearing with slider seat Outer spherical ball bearing with suspension seat External spherical ball bearing with suspension seat Outer spherical ball bearing with adjustable diamond seat Outer spherical ball bearing with stamping seat Outer spherical ball bearings with other seats Features of the outer spherical surface of stainless steel bearings Stainless steel outer spherical bearings are widely used, and the application environment is also very harsh, such as dirt, dust, humidity and high temperature environment. The following is mainly stainless steel bearing outer spherical features 1, stainless steel belt seat spherical bearing can work in the case of two bearing seats are not coaxial, the maximum automatic adjustment Angle of up to 2°. 2, stainless steel belt seat spherical bearing with good rotation accuracy; Easy to re-lubricate. The clearance is larger than that of the same size deep groove ball bearing, so the temperature difference has less influence on its accuracy. 3. The inner diameter of the outer spherical bearing of the stainless steel belt 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, reducing the accuracy requirements of the shaft, and it is very convenient to install or replace the bearing. 4, stainless steel belt seat outer spherical bearing 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, stainless steel belt seat spherical bearings are generally pre-filled with grease, using double or three layers of seal form, suitable for use in dust, mud, corrosive media more occasions, conducive to the work of the host. 6, stainless steel bearing seat for the overall structure, bearing capacity is large, good rigidity, bearing and bearing seat can be exchanged, that is, the same bearing seat can be installed various types of bearings; Similarly, various types of bearing seats can be selected for the same bearing.

The main role of hub bearing is to load and provide accurate guidance for the rotation of the hub, it bears both axial load and radial load, is a very important component. The traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of bearings are carried out on the automobile production line. This structure makes it difficult to assemble in the automobile production plant, high cost, poor reliability, and the car in the maintenance point maintenance, but also need to clean, oil and adjust the bearing. Hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings, it will be two sets of bearings as one, with good assembly performance, can be omitted clearance adjustment, light weight, compact structure, large load capacity, for sealing bearings can be loaded in advance grease, omit the external hub seal and free from maintenance and other advantages, has been widely used in cars, There is also a trend of gradual expansion of applications in heavy-duty vehicles.
