Simple installation, different lamps can be equipped, and the number of lamps can be increased or decreased freely. When there is no limit to the number of lamps installed on the track, it can theoretically not exceed the wattage of the transformer power supply.

The demand for shopping malls using various mechanical equipment and instruments for rolling bearings is becoming more and more stringent; the conditions and functions required for bearings are becoming increasingly diversified. In order to be able to select the most suitable bearings from a large number of layouts and scales; A kind of viewpoint research. When selecting a bearing; usually; thinking about bearing placement, installation, ease of disassembly, bearing space, scale and bearing mallarity of the bearing; roughly determining the bearing layout. Secondly; On the one hand, we will discuss the various life-threatening limits of the various bearings used in bearings and the different endurance limits of the bearings; while determining the bearing scale. When selecting the bearings; tend to only consider the fatigue life of the bearings; The smooth fat life, wear, noise, etc. of the attack also need to be fully discussed. Again; based on different uses; it is necessary to select the requirements for precision, clearance, cage layout, smooth grease, etc.; However, there are no necessary orders and rules for selecting bearings; the priority should be considered for the conditions, functions, and most relevant requirements for bearings. Term; particularly practice. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
