[A] size limit. The usually imported bearings can be mounted in the space is restricted. In most cases, the shaft diameter (or imported bearing diameter) is based on the mechanical design or other design restrictions. The choice of the type and size of imported be arings is determined according to the inner diameter of the imported bearings. Thus, the main dimensions of the scale imports bearing table are prepared according to the international scale diameter size.ball roller bearing
Scale the size of the imported bearings many forms, mechanism design is preferred scale imports of bearings (design to import bearings for easy procurement, in an aside, some entrance models imported bearings catalog does, but some non-standard imports bearing no spot in mainland China, sometimes futures will be a long time, so to consider the time cost and the capital late replacement in the imports of bearing selection) imported bearing the load, load applied on imported bearings, its nature, size, orientation is changeable. Typically, the basic rated load size table are displayed. Axial load and radial load, is to select the appropriate import bearings important factors. When th e size of the ball and needle bearing imports proportionality, needle roller imported bearings usually have a higher load capacity to withstand vibration and shock loading.
[Two], speed, promised to speed is based on the the imported bearing type, size, precision, cage type, load, lubrication, and cooling method and other factors to determine. Imported bearings table lists the the scale precision imported bearings under oil lubrication and grease lubrication promised speed. Typically, deep groove ball bearings, self-aligning ball bearings and cylindrical roller bearings together for high-speed operation of the occasion.spindle bearing
[Three], imported bearing tolerances, dimensional accuracy and rotational accuracy of imported bearings according to ISO and JIS scale. For applications requiring high-precision and high-speed operation of machinery, it is recommended to use five or more precision impo rted bearings, deep groove ball bearings, angular contact ball the imported bearings or cylindrical roller bearings, while for high running accuracy machinery. Rigid, elastic deformation when the pressure on the imported bearings move the body and the contact surface raceway. Some machines require the elastic deformation is minimized. Roller imported bearings imports than ball bearings produced small elastic deformation.
[4], in some cases, imports bearing a preload to increase rigidity. This procedure is usually used for deep groove ball bearings, angular contact ball bearings and tapered roller bearing inner and outer rings bias, shaft bending, shaft or imported bearing housing tolerances change, with the error will lead to the eccentricity of the inner and outer rings. The to prevent eccentric angle through large, automatically aligning ball bearings, self-aligning roller bearings, aligning bearing is the better choice. Voice frequency and torque to move the imported bearings are produced in manufacturing of high-precision scales small voice and torque. Deep groove ball bearings and cylindrical roller bearings combined low voice, low torque requirements of the occasion.
[5], installation and dismantling, some applications often need to be demolished and installed to ensure that in accordance to the detection and repair. Inner and outer rings can be imported bearings were installed, such as: cylindrical bearings, needle roller bearings, and tapered bearings very combination of this occasion. The cone pass self-aligning ball bearings and self-aligning roller bearings sleeve helping the same simplified installation procedure.precision ball bearing
