IKO deep groove ball bearing radial clearance measurement

How to measure the deep groove ball bearing radial clearance, when it comes to choosing IKO bearings with a taper hole would have to request with the amount of interference is bigger than cylindrical hole. Because when there is a greater amount of interference, it could cause the decrease of radial clearance, so when the choice should consider the reduction of radial clearance. First to learn about the concept of the radial clearance, radial clearance refers to the inside of the bearing radial clearance, is to allow the tight fit after assembling, under normal conditions there are plenty of internal clearance. Equipment working in high temperature environment, often also need high temperature resistance, large clearance of IKO bearings with to run. In the process of measuring IKO bearing radial clearance, to ensure that the ball fell into the ditch; For the closed type to measure in front of the closed; When using lotus instrument to measure its, measurements should also be minus load caused by the clearance increase. When the measured object is more columns ball type, insist on measured values of every column clearance should be qualified, and then pick up the columns clearance arithmetic mean as deep groove ball bearing radial clearance. When there are conditions, the best is to use special instrument measuring method. When you need to push method is used to measure, insist on people have higher measurement skills, because the method measuring error is larger, especially clearance are in a state of the edge, it is easy to cause error. When the instrument measurement shall prevail. When feeler method is adopted according to the provisions of the standard and shall not use the roller from feeler on rolling method to measure of the past.
