Explanation of the TIMKEN bearing import specific usage

【 A 】 , size limit. TIMKEN bearing import 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 bearing type and size of the choice is determined according to the inner diameter of the bearing. Thus, the main dimensions of the scale bearing table compiled by the diameter is according to the international scale. Measure the size of the TIMKEN bearing import form is various, in the machinery design is best used when scale bearing ( This design to the bearing is easy to purchase, just as an aside, here some entrance bearing model does have a catalogue, but some non-standard bearings in mainland China there is no spot, some futures will be a long time, so in the late time capital should consider when bearing type selection and replacement of capital) 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 of proportion, needle roller bearing is usually have higher load capacity and bear the larger vibration and shock loads. 【 2 】 , rotational speed, promised to speed is depending on the type of the TIMKEN bearing import, size, precision, cage type, load, lubrication, and cooling way. Bearing table lists the dimension precision bearings under oil lubrication and grease lubrication promised to speed. Usually, deep groove ball bearings, automatic self-aligning ball bearings and cylindrical roller bearings are used in high speed occasions. 【 Three 】 Tolerance, TIMKEN import bearing, bearing dimensional accuracy and rotation accuracy is according to ISO and JIS scale. 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 bearings are used in high running accuracy mechanical. Rigid, when bearing to move body and 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 [ 4 】 And in some cases, TIMKEN bearing import to exert 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 through the large, automatic self-aligning ball bearings, automatic self-aligning roller bearings, or self-aligning bearing seat is a better choice. Voice frequency and torque, move bearing according to produce high precision measure is made, 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. 【 5 】 , installation and removal, some applications often need to disassembly and assembly, to ensure that can according to the testing and maintenance. Can be installed separately on inner and outer bearing such as: cylindrical bearings, needle roller bearings, and tapered bearing fits for this occasion. Taper groove of automatic self-aligning ball bearing and spherical roller bearing under the help of shaft sleeve, also simplifies the installation program.
