How to choose the type and type INA bearing

Select the INA bearing according to the size of INA bearings, specifications, and speed and so on to the INA bearing whether conforms to the scope of the use of our machinery, here is a simple analysis:
First, the limitation of size.
INA bearings can usually installation space is restricted. In most cases, the shaft diameter (or INA bearing diameter) is based on the mechanical design or other design constraints. So INA bearing type and size are selected according to the inner diameter of the bearing and the decision of INA. Thus, the main dimensions of standard INA bearing table according to the international standard diameter size and the preparation of the.
Size form standard INA bearings in machine design is various, the best use of the standard INA bearings (this design to the INA bearing is easy to buy, here as an aside, some INA bearing catalog model does, but some non-standard INA bearings in Chinese mainland area without spot, sometimes futures will be long time, so in INA bearing selection must consider the time cost and a late replacement cost) INA bearing load, applied on the INA bearing load, the nature, size, direction is changeable. Typically, the basic load rating are displayed in the dimension table. Axial and radial loads and so on, are also important factors for the selection of INA bearing. When the ball and roller bearings INA when the size of the load capacity of INA, needle roller bearings typically have a higher vibration and shock loads and withstand greater.
Secondly, speed.
Allowed speed according to the type and size of INA bearings, precision, cage type, load, lubrication, and cooling method to determine factors. INA bearing table lists the standard precision INA bearings in the lubricating oil and grease lubrication allows speed. Usually, INA deep groove ball bearings, self-aligning ball bearings and cylindrical roller INA INA bearings are suitable for high speed operation of the occasion.
Again, INA bearings.
INA bearings are precision of size and rotation accuracy is based on the ISO and JIS standard. For the requirement of high precision and high-speed operation of the machinery, recommend the use of INA bearings are precision of level 5 or above, deep groove ball bearings, thrust ball bearings or cylindrical roller bearings are suitable for high running accuracy of machinery. Rigid, when the roller and raceway contact surface pressure of INA bearing, can generate elastic deformation. Some machines need to keep to a minimum the elastic deformation. Roller bearings are produced than ball bearing elastic deformation of small INA.
In addition, in some cases to exert preloading of INA bearings to increase rigidity. This procedure is usually used for deep groove ball bearings, thrust ball bearings and tapered roller bearing inner ring and the outer ring of the bias, bent shaft, shaft or bearing box changes with INA tolerance, errors will cause the eccentricity of the inner and outer rings. In order to prevent the eccentric angle is too large, self-aligning ball bearings, self-aligning roller bearings, or self-aligning bearing seat is the better choice. Voice frequency and torque, the rolling bearing is according to the high standard of precision manufacturing, so the noise and small torque. Deep groove ball bearings and cylindrical roller bearings, suitable for low voice, low torque occasions with special requirements.
Installation and disassembly, some applications require frequent disassembly and installation, to ensure that can detect and repair regularly. The inner ring and the outer ring can be INA bearing are respectively installed such as: cylindrical bearings, needle roller bearing, tapered roller bearing and is very suitable for this occasion. Self aligning ball bearings taper hole and automatic INA roller bearing in the axle sleeve's help, but also simplify the installation program.
