Compared with the usual mechanical parts; the precision of the linear bearing is high; therefore, it should be carefully handled when using it. 1. Adhere to the sanitary requirements of the German INA bearing and its surroundings. 2. Careful and careful when using it: If used, the thick lobes are imported to the INA bearing. With fierce impact; the bearing will be scratched, indented, cracked and other injuries. 3, the use of appropriate things. 4, focus on the bearing rust. Should be prevented in wet places; and not to sweat; should wear Gloves. 5, the user should understand the bearing. 6, the standard operating standards for the use of linear bearings: 1), INA bearing storage 2), the removal of bearings and their surroundings 3), the size of the equipment parts and the inspection of processing quality 4) 5), equipment operation 5), equipment inspection 6), unpacking operation 7), protection protection (timed viewing) 8), smoothing agent compensation The following table lists the primary analysis items: Analyze project selection method 1, just function Satisfied with the required rigidity of the mechanical shafting type of bearing in the machine tool spindle and the final stage of the vehicle deceleration equipment; together with the rigidity of the progressive shaft; it is also necessary to improve the rigidity of the bearing. The roller bearing receives the load. The shape is smaller than the ball bearing. Preloading (negative clearance) on the bearing can improve the rigidity. The German INA bearing method is applicable to the angular touch ball bearing and the tapered roller bearing. 2. The equipment space of the imported linear bearing can be accommodated in the bearing equipment. The bearing type in the space pays attention to the rigidity and strength of the shaft when drawing the shaft system; therefore, the shaft diameter is usually determined first; that is, the bearing inner diameter. However, the rolling bearing has various scale series and types; the most suitable bearing type should be selected from it. 3. Rotation Bearing type with the required rotation accuracy The machine tool spindle, gas turbine and control machine are required to have high rotation precision, high speed and low conflict. At this time, INA bearings with a precision of 5 or higher should be used. 4. Equipment and disassembly timing check, etc. Cylindrical roller bearings that can be separated by inner ring and outer ring; needle roller bearings and tapered roller bearings are more convenient. Conical hole self-aligning ball bearings INA bearings and tapered holes Spherical roller bearings can be easily assembled and disassembled by using fasteners or withdrawal sleeves. 5. The bearing size, direction and nature of the load bearing load are changed; for example, the load is huge. Whether radial load, axial load is one-way, two-way, oscillation or impact degree, etc. After thinking about these factors; then choose the most suitable INA bearing type. 6, inner and outer ring Relatively skewed to analyze the factors that make the inner ring and outer ring of the bearing relatively skewed; and select the type of bearing that can be used to this kind of application condition. If the relative skew of the inner ring and the outer ring is too large; the bearing will be damaged due to the internal load. The type of bearing that can accept this kind of skew should be selected. 7. The speed limit of the German INA bearing type bearing that can be used to the mechanical speed is not limited to the bearing type but also the bearing scale, the bracket type, the accuracy grade, the load condition and the smoothing method. Therefore, it is necessary to think about these elements when selecting. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
