From the point of view of long-life, INA imported bearing selection requirement is:

INA Bearing Model
 
(1) the high load capacity
INA INA Bearing the price of imports of bearing selection should take into account, or high load capacity, but expensive INA Bearing, or in respect of imports of ordinary INA bearings while the other managed to extend its life.

High load capacity of INA Bearing, for example, with a convex cylindrical roller bearings, spherical roller bearings with symmetrical roller, reinforced tapered roller bearings and ball bearings, ball bearings ball groove bus Correction or 70000CD series INA imported bearings instead of the deep groove (single heart) ball bearings, INA Bearing these high load capacity due to the improved stress distribution, or the number of rolling bodies are more likely to have higher fatigue life .

(2) select the appropriate INA Bearing Size

For INA imported to bearing size selected suitable must be accurate calculation of the actual check of INA Bearing load, speed and operating temperature.

Maximum load INA Bearing life, so load the most difficult measurement but also as far as possible the measured accurately. Measurable motor when the load measurement difficulties, the actual consumption of power, and the deduction of losses along power transmission line projections, until the calculated closer to the actual INA Bearing load. Calculated or measured load is too large INA imports bearing fatigue life expectations must be reduced with greater amplitude, we must seek to remedy. If the installation site allows optional size freshman profile INA Bearing; radial size is limited, the case of imports of a wide INA bearings should be selected wide INA Bearing INA imports; If you can not use a wide bearings could be replaced by a higher load carrying capacity of the INA Bearing.

(3) select the appropriate INA Bearing Materials

Select INA Bearing materials must also take into account its price, and when the vacuum smelting or remelting of steel had to pay attention to the perfection of lubrication conditions, in order to exponentially increase the INA Bearing the expected fatigue life. Of course, higher costs than the choice of load capacity, choose to use these high-quality steel system INA Bearing INA imported bearings are much more expensive, but difficult to close in the machine and is extremely difficult to disassembly INA Bearing, or in mines, tunnels INA Bearing in operating machinery, maintenance extremely difficult occasions, at times they must be considered.
