Source: bearing | last updated: - 2020 07 - 03 you know non-standard bearing manufacturer production of bearing clearance and precision have to distinguish? Non-standard bearing radial clearance of the bearing clearance analysis is divided into the original clearance, clearance and installation work clearance. Often the original bearing radial clearance is greater than the bearing clearance at work. Clearance is one of the important technical parameters of the bearing, it directly influence on the performance of the bearing technology, such as load distribution, vibration, noise, friction, and service life of mechanical motion precision. Strictly speaking, the dynamic load rating of bearing will changes with the size of the clearance. The rated load (listed in the catalogue C and C0) Is the work load value of the gap is zero. If the clearance is too large, the bearing internal bearing area will reduce, on the surface of the rolling contact stress increases, the movement of the bearing will reduce the accuracy, vibration and noise will increase, the service life of the bearing will be shortened. In the process of operation, and may even lead to bearing 'bite'. Therefore, depending on the type of bearing and working conditions to select different levels of the bearing clearance is very important. Standard non-standard bearing internal clearance to C2, standard ( CN） , C3, C4 and C5, met GB4604. Non-standard bearing it is divided into dimensional accuracy and precision rotating accuracy, precision level can be divided into five levels: P0, P5, P6, P2 and P4, P0 level from the beginning. Will P0 non-standard bearings for special purposes will be enough. For some specific condition or situation, must use the P5 or higher precision bearing. Non-standard bearing dimensional accuracy related to the installation of the shaft and bearing seat, usually refers to 1. Bearing inside diameter, outside diameter, width and the allowable deviation of the width of the assembly; 2. Chamfer size allowed limit; 3. Allow the width of the change. The rotating precision of non-standard bearing and the bearing of the rotator: 1, allowing the inner ring and outer ring along the radial and axial running; 2. Inner ring allows transverse beat; 3. Allow the change of outside diameter surface of slope.
