INA drill bearing installation maintenance problems

According to relevant data show that when installing the drill bearing damage accounted for twenty percent of bearing damage, how can we reduce when installing bearing damage? The following details for you when installing INA bearings have specific request for site, site must be kept in dry cleaning, beware of scrap iron, sand, dust, water, into the bearing. Bearing common installation tools have a hammer, tongbang, socket, special plate, screw the mosquito jig, press, etc. , measuring vernier caliper, micrometer, dial gauge, etc. , but according to different models to select different tools of INA bearings. After choose the right tools, can on the drill bearing installed, when installation should pay attention to have no bruising, rust layer, abrasive dust, sand, dust and dirt, can cause installation difficulties, if any have to keep the surface of bearing assembly and cooperate with the surface of the parts are clean. Bearing installation considerations have the following 6 points: 1, assembling on site must be kept clean. INA bearing operation and service life is vital, to avoid bearing from dust, moisture and contaminants - Contaminants. 2, check the bearing hole and shaft with the surface, such as geometry and dimensional accuracy, and cleanliness. 3, in the bearing ring mating surface coated with a little oil or a little fat. 4. Shaft and bearing hole has a 10 degrees - Guide the chamfering of 15 degrees. 5, condensation of water will lead to the matching of the bearing and the bearing surface rust, so don't be too cool bearing. 6, after installation to the drill bearing loading lubricant, check whether the bearing configuration is working properly. Bearing heating temperature to INA bearing size, the required amount of interference. Hot charging work related matters needing attention, the following points need to note: 1, will not be bearing heated to 120 degrees Celsius above; 2, to make the bearing is not direct contact with the bottom of the tank, it is best to consider put drill bearing metal two stage, or bearing hung; 3, will the drill bearing heating to 20 - higher than the required temperature 30 degrees Celsius, so that does not occur in the operation of inner ring cool, difficult to install; 4, after installation, INA bearings cooled down, width contraction, so use shaft nut, or other appropriate method, make it tight, in case of gap between inner ring and bearing retaining shoulder.
