☆ product features Thrust ball bearings from the shaft lap, seat ring, and the ball cage, with the axis line called the ferrule axis circle, with matching shell known as the Ring seat, the seat of the installation of spherical surface Bearing aligning with the performance, reduce installation error. Thrust ball bearings are mainly used under axial loading, you can transfer large axial loads, and can not afford radial load. Such bearings are mainly used in automobile steering mechanism, machine tool spindle, and so on. ★ product categories ZWZ production of thrust ball bearings can be divided into two types: One-way thrust ball bearings Two-way thrust ball bearings One-way thrust ball bearings Axis consists of a circle, a steel ball and seat - to maintain aircraft components. Detachable bearings, shaft lap, seat ring, the ball - to maintain aircraft components can be installed separately. Can be divided into three types: With flat seat thrust ball bearings With self-aligning ball bearing thrust seat Aligning seat belt and seat-aligning ball bearing thrust washers One-way thrust ball bearings are mainly used to bear one-way axial load and to make a one-way axial position. Two-way thrust ball bearings Axis consists of a circle or two seat, a central circle and the ball - to maintain aircraft components. Detachable bearings, shaft lap, seat ring, the ball - to maintain aircraft components can be installed separately. Can be divided into three types: With flat seat thrust ball bearings With self-aligning ball bearing thrust seat Aligning seat belt and seat-aligning ball bearing thrust washers Two-way thrust bearings ball bearings can withstand a two-way axial load, and two-way axial position.   Mid-size range ZWZ the basic thrust ball bearings sizes are listed in the table, Diameter size range: 25mm ~ 1380mm Outside diameter size range: 42mm ~ 1540mm Size range width: 11mm ~ 160 mm   ● Tolerance ZWZ standard thrust ball bearings have a general level, P6, P5, P4-class level of accuracy, in line with national standards. ◇ Cage Cage used the general press plane, physical structure of the two aircraft, if specific requirements are also available to keep other aircraft. When the bearings D ≤ 250mm diameter, using steel plate (with) punching Cage, Cage's code did not post signs. When the bearing diameter D> 250mm, the use of brass entity Cage, Cage's post-code does not sign, sign the rest of the post code. ◆ Minimum axial load Thrust ball in the running, plus if the load is too small, not pressed axial, centrifugal force due to the role of the ball will slip and damage the normal functioning of the bearings. To prevent that from happening, and thrust ball bearings at work must be imposed on minimize axial loading. Famin. Famin = 5.1 () Of which: Famin: the required minimum load??? [KN] n: to r / min C0a: basic static load rating [KN] Point of view to allow error Thrust ball bearings supporting the two must be parallel to the surface, does not allow any deviation. Spherical seat washers and spherical thrust ball bearings have the mental tune, you can reduce the installation point of error. □ equivalent dynamic load P = Fa [KN] ■ equivalent static load P0 = Fa [KN]
