The market requirements for various mechanical devices […]
The market requirements for various mechanical devices and instruments using rolling bearings are becoming increasingly stringent, and the conditions and performance required for the outer spherical bearings are becoming increasingly diverse. In order to be able to select a suitable outer spherical bearing from a large number of structures and sizes, it is necessary to study from various angles. When selecting a bearing, generally consider the arrangement of the outer spherical bearing as the shafting, the ease of installation and disassembly, the space allowed by the spherical bearing of the bearing, the size and the marketability of the outer spherical bearing, etc., and the bearing structure is roughly determined. Secondly, the bearing dimensions are determined while comparing the design life of various machines using bearings and the various endurance limits of the bearings.
When selecting a bearing, it is often only necessary to consider the fatigue life of the bearing. The life, wear and noise of the grease bearing caused by the aging of the grease also need to be fully studied. Furthermore, depending on the application, it is necessary to select bearings that are specially designed for accuracy, NTN bearing clearance, cage structure, grease, etc. However, there is no order or rule for selecting outer spherical bearings. It is especially practical to consider the conditions, performance, and related matters required for the bearings.
