The accuracy and usage of deep groove ball bearing and classification is introduced

The accuracy and usage of deep groove ball bearings, source and classification of bearing | last updated: - 2020 04 - 02 precision of deep groove ball bearings are divided into dimensional accuracy and rotation accuracy, precision grade can be divided into P0, P6, P5, P4, P2 five grades, from P0 began to improve. The special purpose use P0 stage deep groove ball bearing is sufficient, for some specific conditions or situations, you need to use the P5 level or higher precision bearing. Deep groove ball bearing dimension precision is associated with shaft and shell installation, generally refers to the 1, bearing inside diameter, outside diameter, width and allowable deviation of the width of the assembly; 2, chamfer size allowed threshold value; 3 and the change of width allowed amount. Deep groove ball bearing rotating accuracy associated with bearing of revolving quantity: 1, inner ring and outer ring allows the radial and axial beat; 2, inner ring allows transverse beating; 3, outer diameter plane inclination to allow changes. Deep groove ball bearing the purpose and classification of deep groove ball bearing inner and outer ring raceway arc shaped deep groove, channel radius is slightly larger than the sphere, its application is very extensive, its design is simple, belongs to the bearing separation type, suitable for high speed, and operation of durable degree is high, almost no maintenance. Below according to the classification to talk about the deep groove ball bearings application: 1, single row deep groove ball bearings, widely used to belong to the separated type, suitable for high speed, with the seal design has joined grease no maintenance, can bear radial load, but also can bear axial load, commonly used in motor, reducer, electric tools, air conditioning, etc. 2, with ball gap deep groove ball bearing with loaded gap deep groove ball bearings, outer ring each have one ball, can be more than the standard products into the larger ball, have a higher radial bearing capacity, but its axial load capacity is small, with a kind of bearing rotating speed is lower than standard deep groove ball bearings, mainly for the automobile gear box, the application of rotation at low speed and heavy load. 3, stainless steel deep groove ball bearing material is not stainless steel, resistant to moisture and corrosion caused by some other medium, mainly used for corrosion protection of environment, food industry, etc. 4, double row deep groove ball bearing design and single product structure is very similar, just a list, in addition to can bear radial load, can also be subject to bi-directional load and use for single row deep groove ball bearing is not enough to carry the load bearing configuration. 5, high temperature occasion products generally its clearance is bigger, 4 times for C5 clearance, can ask grace will technical personnel, can be used to - 40 - - The temperature range of + 250 degrees. ”
