Non-standard bearing condition requirements and technical countermeasures

Not to mention the carbon content, hardness, wear resistance, roughness and consistency of steel balls and ferrules.
Regardless of the specific appearance, there are ferrous metal cages, non-metallic cages and non-ferrous metal cages.
MC1, MC2, MC3, MC4 and MC5 can be selected according to the fit tolerance;
The accuracy of P0, P6, P5 and P4 can be selected according to the purpose;
Hundreds of greases can be selected from high temperature to low temperature according to working conditions, and small pictures are attached at will:
In this sense, we say that bearings are not standard parts.
According to the specific use conditions, I can provide 608 bearings with different performance for your choice. In order to standardize, the parameters of bearings (size, sealing form, retaining frame material, clearance, oil, grease, etc.) should be limited.
Conclusion: For non-standard bearings, they cannot be simply regarded as standard parts, but the meaning of non-standard parts should be understood. Then, I will give you a diagram of bearing condition requirements and technical countermeasures. Only by knowing the working conditions of your own products can you choose the right products.
Thrust cylindrical roller bearing.
It is composed of washer raceway ring (shaft ring, seat ring), cylindrical roller and cage assembly. Bearing type Full-cylinder roller is produced and processed with convex surface. The pressure distribution on the roller and raceway surface is uniform. It can bear one-way axial load, with large axial load capacity and strong axial stiffness.
Application field: oil drilling rig, iron and steel machinery.
Thrust needle roller bearing.
The separated non-standard bearing is composed of raceway ring, needle roller and cage assembly, which can be combined with the stamping of thin raceway ring or cutting of thick raceway ring. Non-release bearing is an integral bearing composed of precision stamping raceway ring, needle roller and cage assembly, which can bear one-way axial load. These bearings take up less space, which is conducive to the compact design of machinery. Most only select the needle roller and cage assembly, while the assembly surface of the shaft and housing is used as the raceway surface.
Application field: transmission of automobiles, cultivators, machine tools, etc.
Thrust tapered roller bearing.
This non-standard bearing is equipped with a round table roller (the big end is spherical), which is accurately guided by the rib of the raceway ring (shaft ring, seat ring). In design, the apex of the cone surface of the shaft ring, race raceway surface and roller rolling surface intersects at a point on the bearing centerline. One-way bearing can bear one-way axial load, and two-way bearing can bear two-way axial load.
One-way application: crane hook, oil rig swivel. Two-way: mill roll neck.
Turntable bearing.
The non-standard bearing of the turntable has high axial and radial bearing capacity, high tilt stiffness and high accuracy, and is suitable for the non-standard bearing configuration in the turntable, measurement and experiment. When installing this bearing, it is necessary to control the torque of the mounting screws.
10、 Rotary table bearing and non-standard customized type.
The turntable bearing can bear large radial load, axial load and overturning torque at the same time. It integrates support, rotation, transmission, fixation and other functions. It is compact in structure, simple in installation and convenient in maintenance. It is usually used in low-speed situations such as lifting machinery, excavators, turntables, wind turbines, astronomical telescopes, tank turrets, and is widely used.
