Protection and conservation
In order to give full play to the bearing and maintain its proper performance for a long time, it is necessary to make sure that the oil-free bearing is regularly protected (timing view). After proper timing review, early detection of problems, to avoid accidents in the first place, to improve productivity and economy is very important. Storage bearings at the factory are coated with the right amount of anti-rust oil and rust-proof paper packaging, as long as the packaging is not damaged, the bearing quality will be guaranteed. However, long-term sliding bearings stored between, intended to be less than 65% humidity, the temperature is about 20 ℃, stored in the shelf above the ground 30cm is appropriate. In addition, the place should be kept away from direct sunlight or contact with the cold wall. Clean the bearings removed to view, the first filming and other composite bearings do a good job of appearance records. In addition, acknowledge the amount of lubricant remaining and sample the lubricant before you clean the bearings.
 a, bearing cleaning points coarse wash and fine cleaning, and the bottom of the container can be placed on the metal grid.
b, rough wash, the top of the oil with a brush to remove grease or sticky objects. At the moment if the rolling bearings in the oil, pay attention to damage due to foreign bodies such as tumbling surface.
c, fine cleaning, rolling slowly in the oil bearing, to be carefully carried out. The general use of detergent is neutral water-free diesel oil or oil, based on the need to sometimes use warm lye and so on. No matter what kind of detergent, should always be filtered to keep clean. After cleaning, apply anti-rust oil or anti-rust grease on the bearing immediately. View and determine In order to determine whether the removal of the bearing can be used from scratch, we must focus on checking its dimensional accuracy, precision, internal clearance and the cooperation of the surface, raceway, cage and seals. Large bearings because they can not be rotated by hand, pay attention to see the body rolling, rolling surface, cage, ribs and other appearance, the higher the bearing the more you have to look more steady. For viewing the results, can be used to master bearing or proficient in judging. Criteria for discrimination vary depending on the mechanical properties and the degree of majorness as well as the viewing cycle.
If the following damage, bearings can not be used from scratch, it is necessary to replace.
1) Cracking and shortcomings of bearing components.
2) raceway tumbling surface peeling.
Bearing maintenance process
1, first remove the wheel, remember to put the screw closed, lost on the trouble.
2, remove the bearing. Some wheels of the core is very tight, the bearing is difficult to remove, the hexagonal wrench (that is, the one that disassemble the screw) to dig it hard, centering, the bearing is very simple and bad.
3, first with a toothbrush will Perlin dirty surface brush off, do not do this step is OK, no difference.
4, some bearing side cover is detachable, while others do not work, first determine whether Perlin is detachable.
5, if it is detachable, it is very simple. With the word fine screwdriver, C ring in the gap, the C ring pry up, and then remove the side cover, just remove the side just fine.
6, if it is not split, it is more complicated matter. Use a corrupt approach. With a fine screwdriver into the seam of the side cover, force the side cover pry up, do not doubt that is so, but this side cover can not be installed back. Just split the side just fine, split both sides destroyed.
7, all the side of the bearing side cover removed, you can start washing Hello. Dump the oil into the bowl and leave the bearing to stir.
