FAG bearing type selection and the main points of the installation work

First, the size of the restrictions. FAG bearings can usually install space is restricted. In most cases, the diameter of axle ( Or bearing inside diameter) Based on mechanical design or other design constraints. So FAG bearing type and size of the choice is determined according to the inner diameter of the bearing. As a result, the main dimensions of the standard FAG bearing table are compiled according to the international standard diameter. Standard FAG bearing the size of the form is various, in machinery design had better use standard FAG bearing ( This design to FAG bearing is easy to purchase, just as an aside, here model does have some bearing on the catalogue, but some non-standard FAG bearing in mainland China there is no spot, futures will be a long time, sometimes to consider when bearing selection so late time cost and the cost of replacement) FAG bearing load, the load on the bearing, the nature, size, direction is changeable. Usually, the basic load rating on dimension table are displayed. Axial load and radial load, and so on, but also important factors is to select a suitable bearing. When the size of the ball and needle bearing fairly, needle roller bearing is usually have higher load capacity and bear the larger vibration and shock loads. Second, speed. According to allow rotation speed is FAG bearing type, size, precision, cage type, load, lubrication, and cooling way. FAG bearing table lists the standard precision bearings allow speed under oil lubrication and grease lubrication. Usually, deep groove ball bearings, automatic self-aligning ball bearings and cylindrical roller bearings are suitable for high-speed operation. Is again, bearing the tolerance. FAG bearing dimensional accuracy and rotation accuracy is according to ISO and JIS standard. For high-precision and high-speed machines, recommend the use of level 5 or above precision bearing, deep groove ball bearings, angular contact ball bearings and cylindrical roller bearing is suitable for high precision mechanical operation. Rigidity, when FAG bearings rolling element and raceway contact pressure, will produce elastic deformation. Some mechanical need to minimize the elastic deformation. Roller bearing is smaller than ball bearings produced by elastic shape variables. In addition, in some cases, FAG bearings are applying preloading in order to increase rigidity. This program is typically used for deep groove ball bearings, angular contact ball bearings and tapered roller bearing inner and outer circle of bias, shaft bending, shaft or the bearing box tolerance changes, mistakes will lead to the eccentricity of the inner and outer ring. In order to prevent the eccentric Angle is too large, automatic self-aligning ball bearings, automatic self-aligning roller bearings, or self-aligning bearing seat is a better choice. Voice frequency and torque, the rolling bearing are based on high precision standard production, so the voice and the torque is small. Deep groove ball bearings and cylindrical roller bearing used for in low voice, low torque has special requirements of the occasion. FAG bearings can usually install space is restricted. In most cases, the diameter of axle ( Or bearing inside diameter) Based on mechanical design or other design constraints. So the choice is based on a FAG bearing type and size of the inner diameter of the bearing. As a result, the main dimensions of the standard FAG bearing table are compiled according to the international standard diameter. The size of the standard bearing form is various, in machinery design had better use standard FAG bearing ( This design to the bearing is easy to purchase, just as an aside, here some model does have a FAG bearing catalogue, but some non-standard FAG bearing in mainland China there is no spot, futures will be a long time, sometimes to consider when bearing selection so late time cost and the cost of replacement) FAG bearing load, the load on the bearing, the nature, size, direction is changeable. Usually, the basic load rating on dimension table are displayed. Axial load and radial load, and so on, but also is important to choose suitable FAG bearings. When the size of the ball and needle bearing fairly, needle roller bearing is usually have higher load capacity and bear the larger vibration and shock loads. FAG bearings after installation, in order to check whether installed correctly, check for running. Small mechanical can rotate with the hand, to confirm whether to rotate smoothly. Check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on. If there is no abnormal can start power operation. Large machinery from manual rotation, so after no-load start immediately cut off the power, machine idle, check whether there is presence of vibration, noise, rotating parts contact, etc. , confirmed after no abnormalities, into power operation.
