The precision of the non-standard bearing grinding can how? Source: bearing | last updated: - 2020 07 - 04 non-standard bearing grinding precision is? It is divided into dimensional accuracy and rotation 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. Non-standard bearing principle of work of non-standard bearing is the most common type of rolling bearing. Basic non-standard bearing outer ring, inner ring, a set of steel ball and a set of cage. Non-standard bearing has two types: single and double column. Deep groove ball structure has two types: closed and open. Non-standard bearings mainly take radial load, but also can bear radial load and axial load at the same time. When it only bear radial load, the contact Angle is zero. Large non-standard bearing radial clearance, with the performance of angular contact bearings, can withstand a larger axial load. Non-standard bearing small friction coefficient, limit rotational speed is high.
