Bearings turn, inner ring and outer ring roll in the pavement, because roller is rolling contact,

running trajectory is dark side, running trajectory attached to the groove surface does not belong to unusual, so in the disassembly of the bearing SKF, please pay special attention and observe the groove running track.

Carefully observe running track, can know that only burden radial load,  bear large axial load, and inherit torque load, or in the case with extreme bearing rigid not equal. Can check whether the accident of bearing and the load installation error is too big, and etc, and becomes a bearing damage shall be investigated for clues as to why. The deep groove ball bearing under various load conditions of production run orbit.

(a) the turn can only bear radial load quantity to track the performance of the ordinary.

(c) ~ (h) shows to track the performance of the bearing have a bad effect, mostly service life is short.

Roller bearings track is the same

(I) is to circle, rotating load to use when cylindrical roller bearing right radial load and the outer ring running track.

(j) is the inner ring and outer ring relative tilt, shaft to track the performance of the bigger deflection, the groove running trajectory, in its vertical load produced in the circle at the exit shading, running trajectory is tilted, double row circular cone roller bearings that inner ring spinning.

 
(K) say that only the radial load burden to track the performance of the outer ring. L show that only by axial load of the track. With the outer circle tilt, relatively large only bear radial load, its running track deviation in two columns rail surface 180.
