How maintenance and repair Bearings

   In order to give full play to the bearing and long maintained its proper performance, you must do a good job of regular maintenance (periodic inspection).
By appropriate periodic inspection, so that early detection of failure to prevent accidents in the first place, to improve the productivity and economic importance.
    Custody
    Bearing at the factory are coated with anti-rust oil and use the right amount of rust-proof paper packaging, as long as the packaging is not damaged, the quality will be guaranteed.
However, long-term storage, to be less than 65% humidity, the temperature is about 20 ℃ under the conditions stored in the shelf 30cm above the ground is appropriate. In addition, the storage place should avoid direct sunlight or contact with the cold wall.
    Clean
    Remove the bearing inspection, photography and other methods to do first with the appearance of records. In addition, to confirm the remaining amount of lubricant and lubricant samples, and then cleaning bearings.
    a, bearing cleaning of rough wash and sperm washing and can be placed in the bottom of the container used metal grid.
    b, coarse wash, brush, etc. used in the oil or grease removal adhesive material. At this point if rotating bearings in oil, attention and other damage due to foreign objects rolling surface.
    c, sperm washing, in the oil slowly rotating bearings should be carried out carefully.
   

Linear Bearing

    Commonly used cleaning agents for the neutral water diesel or kerosene, is sometimes necessary to use warm lye. Regardless of what kind of cleaning agent filter should always be kept clean.
    Cleaned immediately after anti-rust coating on the bearing grease oil or rust.
    Inspection and judgment
    In order to determine whether the re-use of the removed bearing should focus on checking the accuracy of its size, rotation accuracy, internal clearance and with the surface, raceway, cage and ring.
    Large bearings rotated by hand because they can not pay attention to check the rolling body raceway, cage, ribs and other exterior surfaces, bearing the importance of checking the more it must be taken seriously.
    On the inspection results, may be used to bearing or bearings were judged proficient.
Determine the mechanical properties and the criteria according to the degree of importance and checking cycles vary. If the following injury, the bearings must not be reused and must be replaced.
   1) bearing parts breakage and defects.
   2) rolling surface raceway material peeling.
   Linear Bearings
   Linear bearings divided into metal and plastic linear bearings linear bearings
Metal Linear bearing is a low-cost production of linear motion system for unlimited travel in conjunction with the cylinder axis. Since carrying the ball point contact with the shaft, so the use of small loads. With minimal friction ball rotation, which can obtain high-precision smooth movement.
