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.

Non-standard bearings: What are the basic concepts and characteristics of deep groove ball bearings?

Non-standard bearing manufacturers said: with the continuous development of China's heavy industry, some parts commonly used in the construction and engineering fields have also surfaced. Deep groove ball bearing is actually a rolling bearing composed of inner ring, outer ring and other parts. Simple structure, durability, environmental protection, firmness, fast running speed, no need for regular maintenance and cleaning. The utility model has the advantages of convenient operation, small friction coefficient and wide application range. Various types of deep groove ball bearings can be used in different parts of the product. The following are the basic concepts and characteristics of non-standard bearing manufacturers:

Maintenance procedures and precautions for thin-walled bearings

Do not install it hard on the ball, which will lead to local overload of the ball and contact surface and premature failure of the bearing. Do not use hammer, screwdriver and other hard tools to hit the bearing surface, which will break or embrittle the outer ring of the bearing.

Understand the thin-wall bearing maintenance procedures

The lubrication purpose of thin wall bearings is to reduce the internal friction and wear of bearings and prevent burning and sticking. The lubrication effect is as follows. Reduce friction and wear. The metal contact is prevented and the friction and wear are reduced in the contacting part of the ring, rolling element and retainer of the bearing. Rolling fatigue life that extends the fatigue life. When the rolling contact surface is well lubricated during rotation, the rolling fatigue life will be extended. On the contrary, if the oil viscosity is low and the lubricating oil film thickness is not good, it will be shortened.
