When we choose a rolling bearing type, we should consider the bearing's working load (size, nature, direction), speed and other requirements for use.
转速较高、载荷较小、要求旋转精度高时宜选用球轴承；转速较低、载荷较大或有冲击载荷时则选用滚子轴承。 1) Ball bearings should be used when the speed is high, the load is small, and high rotation accuracy is required; roller bearings are used when the speed is low, the load is large, or there is an impact load.
轴承上同时受径向和轴向联合载荷，一般选用角接触球轴承或圆锥滚子轴承；若径向载荷较大、轴向载荷小，推力罩壳轴承厂商，可选用深沟球轴承；而当轴向载荷较大、径向载荷小时，可采用推力角接触球轴承、四点接触球轴承或选用推力球轴承和深沟球轴承的组合结构。 2) The bearing is subject to both radial and axial combined loads. Generally, angular contact ball bearings or tapered roller bearings are used. If the radial load is large and the axial load is small, the thrust housing bearing manufacturer can choose deep groove ball bearings. ; When the axial load is large and the radial load is small, thrust angular contact ball bearings, four-point contact ball bearings or a combination structure of thrust ball bearings and deep groove ball bearings can be used.
各类轴承使用时内、外圈间的倾斜角应控制在允许角偏斜值之内，推力罩壳轴承，否则会增大轴承的附加载荷而降低寿命。 3) When using various types of bearings, the inclination angle between the inner and outer rings should be controlled within the allowable angular deflection value, and the thrust housing bearing, otherwise it will increase the additional load of the bearing and reduce the life.
刚度要求较大的轴系，宜选用双列球轴承、滚子轴承或四点接触球轴承，载荷特大或有较大冲击力时可在同一支点上采用双列或多列滚子轴承。 4) For shaft systems with large stiffness requirements, double-row ball bearings, roller bearings or four-point contact ball bearings should be selected. Double-row or multi-row roller bearings can be used on the same fulcrum when the load is heavy or there is a large impact . The high rigidity of the bearing system can improve the rotation accuracy of the shaft and reduce vibration noise.
为便于安装拆卸和调整间隙常选用内、外圈可分离的分离型轴承（如圆锥滚子轴承、四点接触球轴承）。 5) In order to facilitate the installation, removal and adjustment of clearances, separate bearings (such as tapered roller bearings and four-point contact ball bearings) with separable inner and outer rings are often used.
选轴承时应注意经济性。 6) Pay attention to economy when selecting bearings. Ball bearings are cheaper than roller bearings.
, 先后开发并生产了一批高质量的带外罩推力球轴承 . 如今御微公司已经走在市场前沿，并具备了较强的行业竞争力。 With the continuous changes of the market and society, the demand for flat thrust ball bearings with covers in more industries is increasing day by day. Yuwei Bearing has closely followed the development pace of the times and has developed and produced a number of high-quality thrust ball bearings with covers . Today Yuwei has been at the forefront of the market and has strong industry competitiveness.
There are two types of thrust ball bearings with housings produced by Yuwei Company. One is with a cage, and the other is a cage without a cage (that is, full of balls). A thrust ball bearing without a cage with a stamped housing It has the characteristics of not being separated, can withstand unidirectional axial load, and has good dustproof effect. Compared with the one-dimensional thrust ball bearing with a cage, the bearing has a large number of steel balls, high bearing load capacity and low limit speed.
生产的带外罩推力球轴承主要用在离合器，液压，电动工具，千斤顶，汽车转向盘。 Shrouded thrust ball bearings produced by Shanghai Yuwei Bearing Co., Ltd. are mainly used in clutches, hydraulics, power tools, jacks, and automotive steering wheels. Most of them are used in automobile accessories. The bearings with this structure are mainly selected in consideration of the characteristics of faster speed, larger load and higher stability.
Taking into account the working environment, Yuwei company produces flat thrust ball bearings with cover can be divided into two types of oiling and grease, high flexibility requirements, you can choose to refuel under the conditions of not too many service life, if the wear resistance Most of the greases that have certain requirements on the nature or the periodicity of use.
的型号大多是根据客户的代号来确定的，不是通用代号，许多都是非标准的尺寸，虽然结构是平面推力球轴承加外罩的形式，但是尺寸会有变化，不过也有些型号比较常见。 The outer thrust ball bearing model of Yuwei Company is mostly determined according to the customer's code, not the universal code, and many of them are non-standard sizes. Although the structure is a form of flat thrust ball bearings plus a cover, the size will change , But some models are more common. 28TAG12 ， 25TAG12 ， 30TAG12 ， 35TAG12 ， 40TAG12 ， 688808K ， 606V,209K ， 202-E ， 201-E 等。 The models are as follows: 28TAG12 , 25TAG12 , 30TAG12 , 35TAG12 , 40TAG12 , 688808K , 606V, 209K , 202-E , 201-E, etc.
