  The Reason Why Self-aligning Roller Bearing Drop Roller

  First of all we may know the three common structures of self-aligning roller bearings are all with small guards on the inner ring, which are distributed on both end faces, and each has a load of roller gaps, with an interval of 180 degrees. The role of the gaps is to facilitate the loading of appropriate rollers.Cages of this kind of structure may generally be made of brass.After finishing the assembly of the finished produc...

  Why radial play and tolerance are not one and the same

  During the Second World War, in a munitions factory in Scotland, a little-known man by the name of Stanley Parker developed the concept of true position, or what we know today as Geometric Dimensioning & Tolerancing (GD&T). Parker noticed that even though some of the functional parts being manufactured for torpedoes were being rejected after inspection, they were still being sent on to production. Upon closer inspection,...
