The accuracy of bearings, that is, dimensional accuracy, shape accuracy, and rotational accuracy, is specified by ISO standards or JIS B 1514 standards. Dimensional accuracy is a necessary item when installing the bearing on the shaft or bearing housing (box), and refers to the inner diameter, outer diameter, width, assembly width, chamfer size and taper tolerance or allowable value. Shape accuracy refers to the allowable value of inner diameter variation, average inner diameter variation, outer diameter variation, and outer diameter average variation. Rotation accuracy is the deflection during specified rotation, which refers to the allowable value of the radial deflection and axial deflection of the inner ring and outer ring, the side deflection of the inner ring, and the outer diameter deflection of the outer ring.
Technology and equipment are the key factors restricting the accuracy of bearings. The precision grades of bearings are from ordinary precision grades JIS grade 0, grade 6, grade 5, grade 4 and grade 2, and the precision increases in turn. The ABEC scale is the tolerance used in the production and manufacture of precision bearings (deep groove ball bearings). Design a set of scales based on uneven levels. This scale is formulated by the Annular Bearing Engineering Association/Committee (abbreviated as ABEC) under the American Bearing Manufacturers Association (ABMA). The predecessor of the American Bearing Manufacturers Association (ABMA) is the Lubricated Bearing Manufacturers Association.
ABEC-1 corresponds to P0
ABEC-3 corresponds to P6
ABEC-5 corresponds to P5
ABEC-7 corresponds to P4
ABEC-9 corresponds to P2
What is the vibration level and scope of application of the bearing?
Bearing vibration (acceleration) is divided into four levels: Z, Z1, Z2, and Z3;
Bearing vibration (speed) is divided into four grades: V, V1, V2 and V3.
Z and V grades are suitable for the vibration inspection of deep groove ball bearings within the range specified by the standard by the bearing manufacturer;
Z1 and V1 grades are suitable for the inspection of finished bearings that have general requirements for bearing vibration;
Z2 and V2 grades are suitable for Y series motors and other motor bearings with corresponding requirements;
Z3 and V3 grades are suitable for strict requirements on vibration. This level has the international advanced level
