Feature of Automobile Alternator Bearing
1)In the structure, each ring of deep groove ball bearing has continuous raceway groove which the
cross section is about a third of the ball girth.
2) When the radial clearance of bearing increases, it will have the properties of angle contact ball bearing,
and it can bear alternating axial load in two directions.
2) Small friction, high speed.
3)Simple structure, low manufacture cost, easy to achieve high manufacture precision.
4)Deep groove ball bearing has as many as 60 variant structures.
