Typical Tolerances of Manufacturing Processes
Typical Tolerances of Manufacturing Processes In the past one of the traditional weaknesses with graduating mechanical design engineers is their inability to select tolerances Most students were reasonably proficient using one or more CAD packages and could produce drawings which were pretty good given their limited experience levels .

Proper Torquing and Runout Tolerances Know Your Parts
But some curb strikes can tweak the flange and cause runout In most cases the wheel and knuckle will deform before the flange or stub axle If a hub or bearing is over torqued it can damage the flange and cause runout It can also damage the bearings and the axle shaft This type of runout cannot be corrected by re torquing the axle nut.
