The choice of bearing's official website: bearing type

Bearing website: the choice of bearing type main point when we choose the bearing type, fully grasp the using conditions of the right is crucial, below, choose by bearing website for us the bearing type of the point. 1, bearing installation space can accommodate in normal installation space bearing type due to the design of shaft system when pay attention to the stiffness and strength of shaft, so generally, first determine the diameter of axle, the bearing inner diameter, but there are various size series and kinds of rolling bearing should choose the most suitable type of bearing. 2, the size of the load bearing load, the direction and nature of the load bearing ability in basic rated load, its value is explained in table bearing size has a bearing load abound change, such as the size of the load, if only the radial load, axial load is a one-way or two-way, the degree of vibration or shock, and so on, after considering these factors, and then to select the most suitable bearing type. In general, the same inner diameter of bearing radial load capacity in the following order: deep groove ball bearings (angular contact ball bearings < < < circular cone roller bearings cylindrical roller bearing, spherical roller bearing. 3, rotational speed can adapt the mechanical speed of the bearing type, speed limit value in limiting speed, can check the registration table size bearing limit speed depends not only on normal type, also limited bearing size, cage form, precision grade, load condition and lubrication method, choose bearing these factors must be considered: most of the following bearings used in high speed rotation: deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings. 4 and has the required rotation accuracy of rotary precision bearing type: dimensional precision and has standardized spindle rotating precision, gas turbine, and control machine, high rotating accuracy, high speed and low friction, at this time should be used more than 5 level precision bearings: general use deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings. 5, just performance meet the mechanical shafting rigid bearing type. When the axial load, part of the rolling element and raceway contact will produce elastic deformation 'high stiffness' refers to the deformation of the elastic deformation smaller reduction device at the end of the spindle and auto parts, such as in improving shaft rigidity at the same time, also must improve the bearing rigidity: roller bearing to bear load produced by small deformation than ball bearings: on bearing preload ( Negative clearance) Can improve the rigidity, the method is suitable for angular contact ball bearings and tapered roller bearings. 6, inner ring and outer ring of tilted relative analysis causes the bearing inner ring and outer ring tilted relative factors, and choose to use this kind of conditions of use of the bearing, the relative tilt is too large, if the inner ring and outer ring of bearing will produce the damage to the internal load, so should choose can withstand the tilt of the bearing type. Generally speaking, allow the slope Angle ( Or the heart) Increasing in the following order: cylindrical roller bearings taper roller bearings < < deep groove ball bearings, Angular contact ball bearing) Spherical roller bearings ( The ball) Bearings. 7 frequency and consider bearing installation and disassembly and installation method; Frequent installation, use of inner ring and outer ring separable cylindrical roller bearings, needle roller bearings and tapered roller bearings, tapered hole self-aligning ball bearing and taper hole spherical roller bearings by using fastening or shirk set can be convenient for installation.
