Machining allowance method for precision mechanical workpiece--TIC
The machining allowance of precision mechanical workpieces can become the blank allowance, which refers to difference between size and design part drawing. Under normal circumstances, we understand it as thickness metal layer cut on surface workpiece ...Read More >>
How long can ordinary miniature bearings be used?
After the analysis of failure, we can know how and from which aspects to stop inspecting miniature bearing that have failed or are about fail. Understanding mechanisms such as erosion fatigue, help eliminate source problem. As long application ...Read More >>
Why are the inner ring of a Miniature Bearing melting with shaft together?
Common occurance problem of the Bearings and solution for them.Why are inner ring a Miniature Bearing melting with shaft together?It may be that fit between hole bearing is loose, resulting in slippage shaft, causing high temperatures to sinter ...Read More >>
Heat treatment process of precision bearings---TIC TECHS BEARING
Preliminary heat treatment:1. Normalizing is to the workpiece Ac3 (Ac refers final temperature at which all free ferrite transforms austenite during heating, generally from 727°C 912°C) or Acm (Acm critical line for complete austenitizing of ...Read More >>
How do you undetstand the bearing life? What are the factors?
Under a certain load, the number of ratations or hours bearing experiences before pitting corrosion is called life.The life rolling defined by ratation (or operation at speed): within this should have initial fatigue damage on any its rings elements. ...Read More >>
Have you judged the bearing quality like this?
