How to measure the radial clearance of deep groove ball bearing, deep groove ball bearings when FAG with taper option requires the interference fit of cylindrical holes greater than. Because when the interference is greater, it will cause reduced radial clearance, so the choice should be considered to reduce the amount of radial internal clearance.
First come to know the concept of radial clearance radial clearance radial, refers to the FAG bearing internal clearance is to allow a tight fit, after assembly, there are plenty of internal clearance in normal conditions. Equipment working in high temperature environment, corresponding to the deep groove ball bearings are of high temperature resistance, high clearance and operation.
In the process of measuring the radial clearance of deep groove ball bearings, to ensure that the ball fell into the ditch; for close to in front of the closed measurement; when the load of the measuring instruments to measure, value should also play minus load caused increase in volume.
When the measured object is a ball type columns, each column clearance requires measurements must be qualified, and then take the train clearance of the arithmetic mean as the radial clearance of deep groove ball bearing.
When there are conditions, the best is the use of special instruments and measurements. The hand pushing method, measuring skills requirements of measuring higher, because this method of measurement error will be large, especially when clearance of marginalized, very easy to cause the error. Then the instruments shall prevail. Using a feeler gauge measurement will be operated according to the provisions of the standard, do not use roller rolling from the past method of feeler gauge for measurement.
