☆ product features Single row angular contact ball bearings from an outer ring, an inner ring, a steel ball, composed of a cage. At the same time be able to bear such bearing radial loads and axial loads, or pure axial load to bear, in a high speed work. Single row angular contact ball bearings in one direction only to bear the axial load. In the radial load to bear, it will cause additional axial force, and can only limit the shaft and a shell in the direction of the axial displacement. Although this type of bearing can only afford a one-way axial load, but with the other in the opposite direction to bear the load bearing portfolio. If the combination is installed in pairs so that the outer ring bearing a pair of relatively the same end, the wide-side face of the wide end (back-to-back DB), narrow-side face of the narrow end (face-to-face DF), so you can avoid additional axial force, but also In both directions so that the shaft or housing restrictions in the axial clearance. Single row angular contact ball bearings mounted ball than the same size deep groove ball bearings, and thus rated load ball bearings in the largest, is also strong rigidity, smooth operation. Can be used both within and outside the circle of mutual adjustment displacement radial clearance and can be caused by parallel sets of bearings have been pre-profit to increase the rigidity of the system. The use of angular contact ball bearings can not be split, its auto-aligning capacity is very limited. Bearing type is characterized by non-zero contact angle, single row angular contact ball bearings have a contact angle of the standard 15 °, 25 °, 30 °, 40 °. The size of the contact angle of the decision bearing work can bear radial and axial force size, the greater the contact angle, and are subject to the axial load capacity of the greater. However, the smaller the contact angle is more conducive to high-speed rotation. Single row angular contact ball bearings is non-existent clearance. Only after the group assigned angular contact ball bearings with only in-house clearance. In accordance with the needs of working conditions, to provide distribution group is divided into pre-load bearing (pre-load) and pre-clearance (pre-clearance) in two ways. Group pre-load contact ball bearings supporting the internal clearance to 0 or negative. Used in the machine tool spindle, the spindle stiffness and to improve the accuracy of rotation. Paired angular contact ball bearing factory clearance (pre-load) has adjusted the user need not adjust. Ordinary single individual angular contact ball bearings the width of the main tolerance and end-stickout only by the general level of production, the combination can not match. ZWZ group is also supporting the production of universal access to ball bearings that can be used back-to-back, face-to-face or in series such as the arbitrary manner distribution group. Provide universal distribution group is divided into pre-load bearing (pre-load) and pre-clearance (pre-clearance) in two ways. In addition to the universal distribution group bearing, the other group equipped with bearings in the bearings do not have a single interchangeability. Such bearings are used for high-speed, high precision, small axial load of occasions. For example, aircraft engine axis, as well as other high-speed machine tool spindle axis of precision machinery. It also applies to high-frequency motor, gas turbine, pumps, air compressors, printing machinery, and so on. Industrial machinery is the most widely used in a class of bearings. ★ product categories ZWZ production of the angular contact ball bearings can be divided into four types: Single row angular contact ball bearings 7000C, 7000AC, 7000A, 7000B Supporting group touch the ball bearings Face-to-face (DB), back-to-back (DF), series (DT), triple Double row angular contact ball bearings Inner Ring Road and two-roll rolling one-two combination of the outer ring Road Outer Ring Road and two-roll rolling one-two combination of Inner Ring Road Double-double with the outer ring raceway inner raceway portfolio Four-point contact ball bearings QJ0000, QJF0000 Single row angular contact ball bearings and ball bearings contact group supporting role In order to improve the angular contact ball bearings and rigid bearing capacity, the same specifications of the angular contact ball bearings, often to double (DB, DF, DT), triple (TBT, TFT, TT), quadruple (QBC, QFC, QT) Even five together (PBC, PFC, PT, PBT, PFT), etc. Distribution Group. On the duplex angular contact ball bearings, the way sub-group equipped with back-to-back (DB), face-to-face (DF), and the tandem (DT) of the three. Back-to-back contact group supporting role in the application of ball bearings under a separate or combined radial and axial load, to be capable of sustaining a two-way axial load. More affordable overturning moment, there is a strong stiffness. Can be used in accordance with conditions imposed by different pre-load. Distribution of the group face-to-face angular contact ball bearings under the overturning moment of smaller, less stiffness provided by the system. The advantage is that bearing on the coaxial error less sensitive. Combination series of angular contact ball bearings to allow only under the direction of a large axial load. In most cases required to impose pre-load spring, to be capable of sustaining the size of the radial load bearing and stiffness of pre-selected depend on the ＆#118alue of the load. Distribution Group is divided into pre-load bearing (pre-load) and pre-clearance (pre-clearance) in two ways. Pre-load: GA - light pre-load GB - in the pre-load GC - heavy pre-load Pre-clearance: CA - small axial clearance CB - middle-axial clearance CC - a larger axial clearance
