It is an important work to identify the specific clearance of bearings. We all know that the quality identification of bearings is more important in many aspects. Let's know how to identify the specific clearance of bearings. The inner ring of the tested bearing is fixed by the fixed seat of the inner ring of the bearing, and the flow rate along the radial direction of the outer ring of the tested bearing is measured, thus the clearance value of the bearing is measured. Clearance is the movement interval of a bearing ring relative to another bearing ring. The clearance value does not conform to the technical standards, which will affect the fair distribution of load between the dynamic elastomers and reduce the rotational accuracy and service life of the bearing.

 

How to reduce bearing failure rate? It is a pivotal factor to determine whether bearing clearance is qualified or not. When in use, the tested bearing is placed flat in the fixed seat of the inner ring of the bearing, the locking nut is tightened, the inner ring of the tested bearing is fixed, and then the percentile meter is fixed on the central line of the measuring tool base with the magnetic table seat and table frame, so that the tip of the gauge contacts and is vertical to the surface of the outer ring of the tested bearing, and the outer ring of the bearing is pushed back and forth by hand. At this time, the oscillating range of the indicator of the percentile is the clearance value of the tested bearing.

 

The commonly used methods of bearing clearance measurement are plug gauge inspection and lead wire inspection, but these two methods make the detection rate of bifurcated lattice bearings low and take a long time. The measuring instrument is composed of base, bearing inner ring fixing seat (upper and lower), locking nut, percentile meter, magnetic table base, table frame and other components.
