Needle roller bearings have realized standardization, serialization and generalization, which are suitable for mass production and supply, and are very convenient for use and maintenance.……

Cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bear radial load. The friction between the rolling body and the ring edge is small, which is suitable for high speed rotation. According to the ring with or without flange, it can be divided i...……

If in the process of installing deep groove ball bearings, the installation method is improper, it will not only lead to the reduction of bearing reliability, but also lead to the early failure of bearings, such as bearing locking fault. What damage will the deep groove ball bear...……

Deep groove ball bearings, formerly known as single-row centripetal ball bearings, are the most widely used rolling bearings. It is the feature of frictional resistance is small, fast, can be used to bear radial load or the radial and axial effect on the mechanical joint load at ...……

Roller bearing clutch is a new type of friction superclutch. Compared with the existing overrunning clutch, it has the advantages of high bearing capacity, long life, reliable locking and so on.……

Needle roller bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. Although there are small parts, bearings still have a higher load capacity, needle roller bearings are equipped with thin and long rollers, so the radial structu...……

The ability of single row tapered roller bearings to bear axial load depends on the contact Angle, that is, the outer ring raceway Angle, the greater the Angle, the greater the axial load capacity. The largest amount of tapered roller bearings is single row tapered roller bearing...……

High speed precision angular contact ball bearings are mainly used in high speed rotating occasions with light load.The installation forms of angular contact ball bearings are back-to-back, face to face and series arrangement.……

Adhesion theory refers to that when two metal surfaces are pressed together, the actual contact point is a series of micro-convex bodies due to the influence of roughness, and the actual contact area is relatively small, so the stress value on the actual contact micro-convex body...……

There are many differences between cylindrical roller bearings and needle roller bearings, and different applications also need to choose different bearings.……

Compared with other traditional axial load measurement methods, the indirect axial load measurement method of ball bearing has many advantages.Ball bearing is one of the most common bearings in the light industry machinery industry.……

Needle roller bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. Although there are small parts, bearings still have a higher load capacity, needle roller bearings are equipped with thin and long rollers, so the radial structu...……
