1, when the bearing running to a period of time (or the guaranteed maintenance period), all bearing down; 2, clean with clean diesel oil or kerosene soaking bearing, if you have open the sealing cover cleaning best technological conditions; 3, dry cleaning oil after cleaning, appearance inspection for damage; Around 4, with a 150 mm, the diameter of the bearing inner diameter equal rods (best is a hollow tube), one end fixed a bearing (see picture); 5, rapidly rotating bearing at the same time with the hand, will stick (wind) on the other end against the ear microphone or audio amplifier on the apology to bearing rotation noise;

After 6, fixed bearing transverse strike sticks, check whether the bearing wear loose phenomenon; 7, loose, the rotation noise is too big, have a serious defect in the bearing should be eliminated, with the same generation; 8, the right amount of a metal drum will grease (high quality) p redictors oil gently melt (not hot), will be tested to no bubble overflow bearings in the bucket. Cooling before take out the bearing grease, residual grease quantity is little.Cools remove bearing grease, residual amount of grease.According to the need to determine how much grease residues. 9, with a soft cloth or wipe toilet paper bearing the grease outside bearing on the same assembly to the pulley, the maintenance work is come to an end. Pour WD40 (rust removing lubricating agent, general large supermarkets or are available at hardware stores, DECATHRON have) or kerosene, Tighten the cap and shake shake repeatedly after a minute or so the bottle vertically about 10 minutes.

1, the characteristics of shortening oil (wel threading) : after using the shortening, bearing is really will go fast fast, especially some bearings have been used for a while, with white oil is soaked, is really can go very fast, this is one of the characteristics of white oil, a word: cool.But white oil has its limits, it is low viscosity, low low will use the white oil, bearing wear resistance decreased obviously, easy to wear and even turn quickly, but listen to the rustle will hear clearly!Generally we use bearing is to ensure that the rotation, are really not very shock, so, for often jump to be cautious with friends shortening.Bought a friend should have some special industrial bearing little bottles of bearings, small bottle with a screw cap, want to use the white oil bubble bearing can put the bearing inside the jar, the oil in this very fuel efficient, and can make the bearing completely bubble inside the bearing, a bottle of $4 white oil, 16 bearing can use 50 to 100 times, is an economical way.

2, grease, daub is relative to the white oil, and is not a bubble, and painted a little less is better.Oil viscosity is large, the bearing rotational resistance is bigger, but the use of oil bearing is durable, not easy to wear and tear.Bought some new bearing, so, sometimes try to turn it, slowly, but very stable, no voice. 1, when the bearing running to a period of time (or the guaranteed maintenance period), all bearing down; 2, clean with clean diesel oil or kerosene soaking bearing, if you have open the sealing cover cleaning best technological conditions; 3, dry cleaning oil after cleaning, appearance inspection for damage; Around 4, with a 150 mm, the diameter of the bearing inner diameter equal rods (best is a hollow tube), one end fixed a bearing (see picture); 5, rapidly rotating bearing at the same time with the hand, will stick (wind) on the other end against the ear microphone or audio amplifier on the apology to bearing rotation noise;
