KA025ARO thin section bearing
ZGCr15 is one of the most commonly used steel for the production of bearing rollers and rings , be of good comprehensive performance and good machinability, hardness after quenching and tempering and even after annealing, high wear resistance and contact fatigue strength, thermal processingperformance of GCr15 steel use and production of high carbon chromium bearing steel grades.
ZGCr15 Executive Army A-61 standard electroslag re-melting the steel, the impurity less than GCr15, and better performance.
ZGC15 ball purposes: for the long life of high-speed precision bearings supporting applies to the machine tool spindle bearings, high-speed rolling mill bearings, machine tool bearings, aerospace bearings and so on.
Angular contact ball bearings are able to support radial load and axial load.As single row angular contact ball bearings can only suport axial load in single direction,matched bearing,mounting is often adopted to them.As matched pair of bearings,preload for them is convenient.Retainers are made of brass,synthetic resins or others subject to individual bearing features and application condition.
Main parameters and calculation of the precision bearings
We have explored and produced various of types and structure of high-speed precision bearings , each bearing has its particular application , it depends on the different working conditions , and the selection need to consider the following bearings performance .
About the angular contact ball bearings , there are diameter series 18,19,(1)0 and (2)0 ; about the ball screw ball bearings, there are diameter series (0)2 and (0)3 . With the same size inner diameter , the corresponding diameter and width of 18,19,(1)0,(0)2 and (0)3 diameter series bearings are in turn increases .
