Angular contact ball bearing outer ring, while thick engraving machine spindle bearing 7002 / P5, while thin. Thick side referred to as "back", referred to as thin side "face." Two combinations: DB portfolio: back to back combinations. High stability, can improve the rigidity of the bearing. DF combination: a combination of face to face. Applies to the long axis of Huiyang District engraving machine spindle bearing, allowing a certain amount of deflection. DT combination: a series combination of (a bearing of the "back" and "face" of a combination of the other bearing). Make a single direction axial bearing axial doubled. Combination of three columns and four rows of combination is based on a combination of the two columns, make up less than two columns portfolio (mostly less than the axial load areas) and combinations produced. For example: DB combined in a single axial direction of the need for greater axial load freshwater engraving machine spindle bearing, you need to add a column next to the bearing, consisting of a combination of three columns. If the axial load in both directions need to increase the bearing, you need to add one on each side, consisting of a combination of four columns. Some common combinations see (below)! Another: bearing manufacturers are producing all kinds of combinations of good bearing, and a single universal bearings. This kind of bearing can limit the axial displacement in one direction or housing. The higher speed limit contact ball bearings can support radial load and axial load can also be subject to pure axial load, axial load capacity by the contact angle, and increases with the contact angle increases.
