With the role of SKF bearings SKF bearings are still making laps and rotations are still part of the installation site (usually bearing) and a rotating part (usually a shaft) consolidation together to achieve the transfer in the rotating state system load and limited movement relative to the stationary system of the basic tasks of the position.
        The shaft and the bearing housing, SKF Bearing requirements for fixed its position in three directions, radial, axial and tangential direction. Radial and tangential positioning tight fit through the mining of SKF bearing rings achieve axial positioning only in a few cases a tight fit; generally limit the use of the axial parts, such as axial end caps and ring, etc. location defined within clearance range.
        Should be selected with the focus on the following four points:
         (1) SKF Bearing rings and circumferential surface should be well supported even by force, in order to reduce distortion, and give full play to the carrying capacity of SKF bearings.
         (2) can not slip rings in its tangential direction with the surface, otherwise it will damage the mating surfaces.
         (3) the free end of SKF bearings must be able to change the length of the shaft and housing bore SKF bearings to adapt, which must have the ability to adapt to the axial position within a certain range of swimming.
         (4) must be taken so that the bearing of SKF easy installation and removal, saving time and labor expenses province.

KOYO bearings factor mainly refers to the installation and adjustment, use and maintenance, repair and other maintenance meets the technical requirements. According KOYO bearing installation, use, maintenance, maintenance of technical requirements for the operation of the bearings to withstand load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find reasons to be adjusted so that its back to normal. Installation conditions is one of the primary factors in the use of factors, bearing often caused by improper installation package bearing the stress state changes between the various parts, bearing in normal operation and early termination of the state of the internal life of the main factors is refers to the structural design, manufacturing processes and materials quality determines the quality KOYO bearing three factors.
       1) KOYO bearing design parameters include: the number of rolling element bearings, rings, such as wall thickness and clearance.
2) manufacturing error KOYO bearing parts: including bearing raceway and the rolling surface roughness, roundness crossing pattern and degree of difference. A large number of experimental studies have shown that the impact of bearing vibration waviness dominates, while the influence of surface roughness and roundness is relatively small.
3) KOYO bearing operating conditions: the bearing during operation, load, speed, lubrication conditions affect three largest KOYO bearing vibration.
4) KOYO bearing installation parameters: the bearing and the shaft and housing fits, installation and other factors are also biased impact on the vibration of the bearing.

1, KOYO bearings installed
     KOYO bearings installed correctly, affecting accuracy, longevity, performance. Therefore, the design and assembly departments to fully study the bearing installation. I hope to be in accordance with the operating standards for installation. Operating standards projects typically as follows:
(1) cleaning bearings and related components;
(2) Check the size and finishing related components;
(3) Installation;
(4) Check bearing installed after;
(5) supplying lubricant.
2, alignment, alignment
     After bearing installation, if not carefully for alignment, alignment may lead to additional load bearing subjected to friction and vibration. These may accelerate fatigue and reduce bearing life, and may damage the life of other machine parts. In addition, increased vibration and friction can significantly increase energy consumption and the risk of premature failure.
3, the basic condition monitoring
     During use, the external conditions should always bearing on the basic operation of the monitor, such as temperature, vibration and noise measurements, and the like. These regular inspections will identify potential problems early and prevent unexpected machine suspension phenomenon, so that production plans are realized, to improve plant productivity and efficiency.
4, re-lubrication
     In the course of the operation, KOYO bearings require a correct re-lubrication, perfect its performance. Bearing lubrication methods, divided into grease and oil lubrication. In order to play well bearing function, first, to select the appropriate conditions, the use of lubrication purposes. If only consider lubrication, oil lubrication dominant. But there can be simplified specialty grease around the bearing structure.
5, Remove
     When KOYO bearing will reach its end-use period of time, it should be replaced. Although bearings can no longer be used, but the right to remove the original bearing, and timely replacement of new bearings, new bearings for extended life can play a good role in promoting. First, the proper way to remove the use of tools that will help prevent damage to other components of the machine, and the second, incorrect technique might be interested in removing the operator hazard.
