(1) Select IKO bearings with high load capacity Model
Bearing IKO Bearing selection should take into account the price, or a higher load capacity but expensive IKO bearings, IKO bearings or in respect of the ordinary and the other trying to extend its life. Uses a high load capacity IKO bearings, such as cylindrical crowned roller bearings with symmetrical rollers Spherical roller bearings, tapered roller bearings reinforced and ball bearings, ball groove ball bearings bus corrected, or 70000CD series IKO bearings instead of the groove (single row radial) ball bearings, which have a high load capacity of IKO bearings or for improving stress distribution, or because of the number of rolling elements which are more likely to have higher fatigue life.
(2) Select the appropriate size IKO bearings
To IKO bearing size chosen, must be accurately calculated or actual check IKO bearings work load, speed and operating temperature. IKO impact load on the bearing life the most, although it loads but also the most difficult to measure as accurately measured. When the load is difficult to measure, measure the actual power consumption of the motor, calculated and deducted by the transmission line power loss along the way until it is closer to the actual calculated IKO bearing load. Calculated or measured load is too large, IKO bearings can expect the inevitable fatigue life with greater amplitude decreases, must try to remedy the situation. If the installation site allows, IKO bearings selectable file size freshman; If the radial size is limited, in case there is a wide IKO bearings IKO bearings should be selected wide; If you can not take advantage of a wide IKO bearings, can be changed bearing with higher load carrying capacity of IKO.
(3) Select the appropriate IKO bearing material
Select IKO bearing material should take into account its price, but when you have to vacuum smelting or remelting of steel, must pay attention to perfect the lubrication conditions to exponentially increase IKO bearings can be expected fatigue life. Of course, the choice of the kind of high-quality steel made ??IKO bearings use a higher load capacity than the cost of IKO bearings is much more expensive, but difficult to close in the machine and difficult to dismantle the IKO bearings, or mine, tunnel operating machinery IKO bearings used, maintenance is extremely difficult situations, sometimes still must be considered.
Bearing failure analysis, in order to improve the reliability of systems engineering work surface IKO important part of the bearing (bearing function of the composition of the work in its loss provisions, resulting in malfunction or failure of the phenomenon known as work (bearing failure can be classified according to their normal two early life failures and failure, which is mainly the reason leading to early bearing failure analysis and suggest improvements to enhance the life and reliability of IKO bearings for pitting and fatigue.
  IKO bearing surface in the form of fatigue failure is a failure, mainly for the initiation of fatigue crack growth and fracture processes in the long-term effects of alternating metal generated under load failure. Cracks in two ways:

First: On the surface, it is in the process of rolling contact, due to exposure to cyclical changes in stress and strain hardening plastic deformation surface work surface caused by the effect of external loads IKO bearings, and finally in small cracks from the inner surface of the development of cracks formed between the surface, the lubricant is wedged into the work surface opening force against the wall crack, crack forced forward;
  II: from the pressure surface layer and repeated contact surface, where the first exposed surface cracks cracks certain depth and angle of the direction along the surface to a certain depth from the rear surface of the contact surface, and beyond surface and eventually formed erosion stripped, leaving a Makeng.
  On the surface, or from cracks in the surface layer, these two goals (parts carburizing, quenching and other surface treatment, if there is uneven hardness, organizations, and non-uniform stress and other negative, then contact stress in general is from the subsurface fractures produce opposite effects, if the part surface quality is poor, there is a defect (oxidation, decarbonization), friction or poor lubrication, the surface cracks.
