Type Selection Requirements For Long Life INA Imported Bearings

 

From the point of view of long life, the selection requirements of ina imported bearings are:

 
(1) Select ina imported bearing model with high load capacity

When selecting ina imported bearings, the price of ina imported bearings shall be taken into account, or ina imported bearings with higher load capacity but more expensive shall be adopted, or ordinary ina imported bearings shall be adopted to prolong their service life. Ina imported bearings with high load capacity are adopted, such as cylindrical roller bearings with convexity, spherical roller bearings with symmetrical rollers, reinforced tapered roller bearings and ball bearings, ball bearings with corrected ball groove bus, or ina imported bearings of 70000cd series are used to replace deep groove (single row centripetal) ball bearings. These ina imported bearings with high load capacity or due to the improvement of stress distribution, Or it may have higher fatigue life due to the large number of rolling elements.

(2) Select the appropriate ina inlet bearing size

In order to select the proper size of ina inlet bearing, the working load, speed and operating temperature of ina inlet bearing must be accurately calculated or verified. The load has a great impact on the service life of ina imported bearings, so although the load is difficult to measure, it should be measured as accurately as possible. When it is difficult to measure the load, the actual power consumed by the motor can be measured, and the power loss along the way can be calculated according to the transmission route and deducted until the bearing load close to the actual ina inlet is calculated.

 

If the calculated or measured load is too large, the expected fatigue life of ina imported bearings must be reduced by a greater margin, which must be remedied. If the installation position allows, ina imported bearing with a larger size can be selected; If the radial dimension is limited, the wider ina inlet bearing shall be selected when there is a wider ina inlet bearing; If the wider ina imported bearing cannot be used, the ina imported bearing with higher load bearing capacity can be used.

 
(3) Select appropriate ina imported bearing materials

When selecting ina imported bearing materials, its price should also be taken into account, and when vacuum smelting or electroslag remelting steel has to be used, it should be noted that the lubrication conditions must be improved in order to double the expected fatigue life of ina imported bearings. Of course, the cost of selecting ina imported bearings made of this kind of high-quality steel is much more expensive than that of selecting ina imported bearings with high load capacity. However, for ina imported bearings that are difficult to access in machines and are very difficult to assemble and disassemble, or ina imported bearings used in operation machinery in mines and tunnels, sometimes they must be considered for maintenance.
