Discussion on the how the selection of KOYO bearing imports

1, on the KOYO bearing size limit.
KOYO bearings can usually installation space is restricted. In most cases, the shaft diameter (or KOYO bearing diameter) is based on the mechanical design or other design constraints. Selection of bearing type and size according to the inner diameter of the bearing and the decision of KOYO. Thus, the main dimension of KOYO bearing table according to the international scale diameter size preparation.
Dimension forms scale bearing numerous, in the design of mechanical device is best when using scale KOYO bearing (KOYO bearing whether this design to easily purchase, here as an aside, some entrance bearing catalog model does, but some non-standard KOYO bearings in Chinese mainland area without spot, sometimes futures will be very long time in the bearing, so the selection must consider the time cost and a late replacement cost) KOYO bearing load, load exerted on the bearing, 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 KOYO bearing. When the ball and needle
Commensurate with the bearing size, load capacity of needle roller bearings typically have a higher vibration and shock loads and withstand greater.
2, in some cases to exert preloading of KOYO 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 KOYO tolerance, errors will cause the eccentricity of the inner and outer rings. To prevent the eccentricity through large, self-aligning ball bearings, self-aligning roller bearings, or self-aligning bearing seat is the better choice. Voice frequency and torque, move KOYO bearings are based on high precision scales to produce, so noise and small torque. Deep groove ball bearings, cylindrical roller combined bearings for low noise, low torque occasions with special requirements.
3, speed, promised to speed depending on the type, size of KOYO bearings, precision, cage type, load, lubrication method, to determine the factors and cooling method. KOYO bearing table lists the accuracy of a scale of KOYO bearings in lubricating oil and grease lubrication of the promised speed. Usually, deep groove ball bearings, self-aligning ball bearings and cylindrical roller bearings are suitable for high speed operation of the occasion.
4, KOYO bearing tolerances, bearing size precision KOYO and rotation accuracy is based on the ISO and JIS scale. For the requirement of high precision and high-speed operation of the machinery, grade 5 or above is recommended precision bearings, deep groove ball bearings, thrust ball bearings or cylindrical roller bearing is used for the high operation precision machinery. Rigid, when the moving body and raceway contact surface pressure of KOYO 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 small.
5, the installation and disassembly, some applications often need to disassembly and installation, to ensure that can detect and repair according to its. The inner ring and the outer ring can be KOYO bearing are respectively installed such as: cylindrical bearings, needle roller bearing, tapered roller bearing is combined and on this occasion. Self aligning ball bearings taper hole self-aligning roller bearing in the axle sleeve and the help, also simplifies the installation program.
