Rotating inner ring and outer ring of the bearing Raceway surface due to rolling is rolling contact, track for the dark side, track attached to the Raceway surface does not belong to an exception, we will load conditions, so remove the TIMKEN bearings cases, strict attention and observation of Raceway surface running track.
If you look closely at the track, you will know that the only burden the radial load, subjected to axial loads, endurance moment loads, or in extreme rigidity does not equal on the bearing box. Can check for adding an unexpected load to TIMKEN bearings and installation errors is too large, and hold clues to the cause of bearing damage. Deep groove ball bearings are produced under different load conditions the running track.
(A) is the inner ring rotates can only take radial loads of ordinary track.
(C) ~ (h) as shown in the running track has a bad effect on bearing, mostly shorter service life.
Track roller bearing are the same
(I) ring rotation load, is the use of cylindrical roller bearing with radial loads correctly when running track in the outer ring.
(J) is the inner ring relative to the outer ring tilt, axial deflection of large running track, Raceway surface running track, in its vertical bias on the exit of the load ring, is inclined to run track, double row tapered roller bearing inner rings rotate.
(K) indicates that only bear the radial load of the outer ring of the track. L only track when subjected to axial load. In the inner ring relative to the outer ring when tilted only take radial loads, its orbital plane 180 running trajectory deviation in two columns. (M).
