(1) select a high load bearing capacity of model import
Bearing selection should take into account the price is quite expensive, but SKF bearings with higher load capacity, or in general use bearings, when seeking to extend its life.
Using with cylindrical roll child bearing roll child Crown of to symmetric spherical roll child bearing of hosted capacity high, such as, strengthening tapered roll child bearing and ball bearing, ball bearing deep groove ball modified car, or 70000CD series, and not deep groove bearing (separate radial) ball bearing, bearing has high hosted capacity of improve, because stress distribution or, or due to scroll body of number more may has high of fatigue life.
(2) select the appropriate size bearing
Elections is the size you want to import the appropriate bearing must be accurately calculated or check the bearing load, speed and operating temperature of the actual work.
Greatest influence on loads of FAG bearings life, while difficult to measure, but it should load an exact measurement. Load measurement is difficult to measure the actual power consumption is projected to reduce the power loss of transmission lines along until the calculation of bearing loads more realistic. Calculating or measuring load is too large, bearing fatigue life can be expected necessarily reduced to a greater extent, must seek to remedy. If you install the site license, an optional size bearing large document; if a radial dimension is limited, there is an extensive case, bearing a wide range should be selected, if you don′t use wide bearing can be changed later with the carrying capacity of the bearing.
(3) select the appropriate bearing materials
NSK bearings material selection should take into account the price, when forced with a vacuum or electro-slag remelted steel smelting, note on a good lubrication conditions, to exponentially increase bearing fatigue life. Of course, this high quality steel used by the system, than of bearing load capacity of bearing selection is more expensive cost, but the machine difficult to close, very difficult to dismantle the bearing, or in mining, tunneling work machinery bearings, maintenance under extremely difficult conditions and sometimes are issues to consider.
