The demand for shopping malls using various mechanical equipments and instruments for rolling bearings is becoming more and more stringent; the conditions and functions required for NSK bearings are becoming increasingly diversified. In order to be able to select the most suitable bearings from a large number of layouts and scales; Various viewpoints. When selecting bearings; usually; thinking about the bearing placement, installation, ease of disassembly, the space, scale and bearing of the bearing as the shafting; roughly the resolution of the bearing layout. On the one hand, we will discuss the various life-defining limits of the various types of bearings used in bearings and the different endurance limits of the bearings; while determining the bearing scale. When selecting the bearings; tend to think only about the fatigue life of the bearings; The aging of the grease life, wear, noise, etc. also need to be fully discussed. Again; based on different uses; it is necessary to select the requirements for precision, clearance, cage layout, grease, etc.; Bearings. However, there are no necessary orders and rules for selecting bearings. The priority should be to consider the conditions, functions and the most relevant requirements for the bearings. Matters; especially practice. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Bearings equipped with bearings have a great influence on bearing rigidity; generally speaking; ball bearings and roller bearings with centripetal thrust type; when used in pairs, it is advisable to adopt the outer end of the outer ring (ie its pressure line) The equipment consists of the pressure cone tip outward; the ability of the bearing to resist the overturning moment is large; the preload amount adjusted during the temperature change is also less likely to change.
As for the needle bearing of the outer ring as long as it is punched; because the outer ring wall is very sturdy, the scent of the scorpion is smashed, the sputum is smashed, and the pressure is uneven; the needle roller bearing is simply The outer ring is partially deformed.
“Plug-inserted†refers to a type of bearing equipment in which each NSK bearing is unidirectionally positioned to the shaft; and the direction is reversed. This combination is primarily used for the short shaft. All radials that accept at least one axial load in one direction Bearings are suitable; including deep groove and angular touch ball bearings, tapered roller bearings and NJ cylindrical roller bearings; when using angular touch ball bearings or tapered roller bearings; in some cases; it is necessary to apply preload.
The shaft is supported by two bearings in radial and axial directions; the bearing on one side is called a fixed end bearing; it accepts both radial and axial loads; the relative axial direction between the fixed shaft and the bearing housing The effect of displacement. The other side is called the free end; only the radial load is accepted; the axial direction can be relatively moved.
Fixed-end bearings need to be fixed together with the shaft and bearing housing; suitable bearings are capable of accepting composite load radial bearings; for example; deep groove ball bearings, spherical roller bearings and double or mating angular contact ball bearings or cones Roller bearings. Radial bearing combinations that accept simple radial loads; such as cylindrical roller bearings with inner and outer rings without ribs combined with deep groove ball bearings or four-point ball bearings or two-way thrust bearings; End bearing. At this time; the second bearing is supplied in two-way axial position; however, it is necessary to maintain a certain radial distance from the bearing housing when the device is installed. The free end bearing is thermally expanded in the shaft; when the length changes, the bearing does not occur. Pinch. Axial displacement can occur inside the bearing; NSK bearing ring and bearing housing can also occur.
