Bearing 3210 Maintenance method
1) when the bearing 3210 running to a period of time (or maintenance), all bearing down;
2)soaking with cleaning with diesel or kerosene cleaning bearing, if you have technical conditions the best open
the sealing cover cleaning;
3)after cleaning, dry cleaning oil, appearance inspection for damage;
4)with a 150 mm and a diameter of angular contact ball bearing inner diameter equal rods (best is a hollow tube),
one end fixed a bearing;
5)rapidly rotating bearing at the same time with the hand, will stick (wind) at the other end against the ear on
the microphone or audio amplifier on apology to bearing rotation noise;
6)fixed bearing transverse strike sticks, check the bearing wear loose phenomenon;
