The bearing with seat can carry out simple and effective automatic centering for installation errors, and can be easily installed on various industrial shafts, especially on the rack of equipment. Bearing seats have a wide range of products, including vertical seats, various flanged seats, keyway seats, circular seats, etc. the materials used include gray cast iron seats, ductile iron seats, steel plate stamping seats, stainless steel seats, plastic seats, etc. What are the characteristics and advantages of pedestal outer spherical bearings?
1、 The outer spherical bearing with seat is composed of outer spherical bearing and bearing seat. There is no need to design a bearing box when using it. It has small size and simple structure. It can be directly installed on the design part of the host with bolts, which is convenient to use.
2、 Simple and practical: the bearing seat is an integral structure with large bearing capacity and good rigidity. The bearings and bearing seats can be interchanged, that is, the same bearing seat can be installed with different types of bearings; Similarly, various types of bearing seats can be selected for the same type of bearing.
3、 Automatic adjustment: the outer spherical bearing with seat can work under the condition of different shafts of two bearing seats, and the maximum automatic adjustment angle can reach 2 °.
4、 Auxiliary accessories: the inner diameter of the outer spherical bearing with seat adopts the "+" tolerance to form a clearance fit with the shaft. The bearing is fixed on the shaft through some jackscrews, eccentric sleeves or tightening sleeves on the inner ring, which reduces the accuracy requirements of the shaft. It is very convenient to install or replace the bearing.
5、 Small requirements for working environment: the outer spherical bearing with seat is generally pre filled with grease and adopts the form of double-layer or three lip seal, which is suitable for use in occasions with more dust, muddy water and corrosive media, which is conducive to the work of the host machine.
6、 Accuracy advantages: the outer spherical bearing with seat has good rotation accuracy.
