Precision bearings are one of the indispensable and important components in modern industry, and their classification and application range are wide. The following will be a brief introduction to the classification of precision bearings and their applications.
First, the classification of precision bearings.
1.Tapered roller bearings
Tapered roller bearings are a common type of precision bearing that is mainly used to withstand radial and axial loads. Its structure is characterized by tapered rollers between the inner and outer rings, so that the bearing has a high load capacity and low frictional resistance. Tapered roller bearings are widely used in various machinery, machine tools, automobiles and other fields.
2.Cylindrical roller bearings
Cylindrical roller bearings are also a common precision bearing, and their structure is characterized by cylindrical rollers between the inner and outer rings. This type of bearing has a high speed and low frictional resistance, which is suitable for high-speed rotation applications. Cylindrical roller bearings are widely used in motors, aerospace, precision instruments and other fields.
3.Spherical roller bearings
Self-aligning roller bearing is a precision bearing with self-aligning function, and its structure is characterized by spherical rollers between the inner and outer rings. This type of bearing is suitable for bearing large axial and radial loads, with high load carrying capacity and low frictional resistance. Spherical roller bearings are widely used in various heavy machinery, mining machinery and other fields.
4.Thrust ball bearings
Thrust ball bearings are precision bearings that bear axial loads, and their structure is characterized by spherical rollers between the inner and outer rings. These bearings are suitable for large axial loads, with high load carrying capacity and low frictional resistance. Thrust ball bearings are widely used in various machine tools, automobiles and other fields.
