What is a bearing? What are the main categories?

We should all be familiar with bearings, which are a very common component in machinery. But do you really understand it? Do you know how many categories it is divided into?

Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

There are many types of bearings, the main categories are as follows.

1. Needle roller bearings

It is a type of roller bearing, but its roller bearings are relatively long and slender. This type of roller bearing is called a needle roller. With small cross-section but strong load capacity, needle roller bearings are equipped with slender and long roller bearings with the smallest diameter, especially suitable for support structures with limited axial installation specifications.

2. Deep groove ball bearings

Deep groove ball bearing is a type of flip bearing. Its advantages are small friction and high speed ratio. It can be used on parts that bear axial load or radial and radial simultaneous loads. It can also be used on parts that bear radial load.

3. Spherical roller bearings

Spherical roller bearings have self-aligning roller bearings. The structure has automatic self-aligning characteristics, so it is not easily affected by the angle deviation between the shaft and the bearing housing or the bending of the shaft. It is suitable for installation deviation or shaft strain. The place of perspective deviation. In addition to the axial load, the bearing can also bear the dual-effect radial load.

4. Thrust roller bearings

Thrust roller bearings can withstand double loads, in which the axial load cannot exceed 55% of the radial load. The friction resistance coefficient is high, the rotation speed is also high, and it has an aligning function.

Thrust spherical roller bearing

5. Linear bearings

Widely used in components of CNC lathes, CNC lathes, textile equipment, printing equipment and other mechanical equipment.

6. Insert spherical bearing with seat

Insert spherical bearing with seat, the bearing and bearing seat are integrated. Most externally curved bearings are made of diameter curved surfaces and are installed together with imported bearing seats with spherical internal threads. They have various structures and have good practicality and tolerance. At the same time, this type of bearing also has a certain degree of alignment in design, is easy to install, has a two-way structural sealing device, and can work in harsh environments. Bearing seats are generally forged. Common seats include column seat (P), square seat (F), punch square seat (FS), punch ring seat (FC), prismatic seat (FL), ring seat (C), and roller seat (T )wait.

7. Spherical bearings

The spherical plain bearing is a kind of curved rolling bearing. Its rolling contact surface is an inner curved surface and an outer curved surface. It can also rotate in any direction during exercise. It adopts surface phosphating treatment, blasting, padding, spray painting, etc. Made with various unique processing techniques. Bone joint bearings have the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, and good lubrication.
