The need to overheat the NSK bearing
LED Sensor Batten Lights has options of microwave sensor and infrared sensor. There are two sensing modes. One is 0-10v dimming, and the other is on/off.
Toggle button can set the remote distance of remote control and sensor.
If you need sensor lights in factories or warehouses, corridors, or other indoors, you can choose this LED Sensor batten lights. If you need IP66 sensor light, you can choose Sensor Waterproof Light.

The professor suggested that our bearing overheating is a sign of bearing problems. The following senior professors will analyze the necessity of inducing overheating of NSK bearings. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
.1) Bearing damage; should be replaced.
.2) The rolling bearing grease is too small, too much or has iron scraps and other impurities. The capacity of the bearing grease should not exceed 70% of the total volume; those with impurities should be replaced.
.3) The shaft and the bearing cooperate too tightly or too loosely. When overtightening, it should be ground from the head; when it is too loose, the shaft should be set.
.4) The bearing and the end cap cooperate too tightly or too loosely. The bearing chamber is machined when it is too tight; when it is too loose, the steel sleeve is set in the end cover.
.5) The two caps or bearing caps of the motor are not properly installed. Install the end cap or bearing cap stop into the flat; tighten the screws.
.6) The belt is too tight or the coupling is not properly installed. Adjust the belt tension; proofread the coupling.
.7) The sliding bearing lubricant is too little, there is impurity or the oil ring is stuck. It should be like refueling or replacing the oil; repairing or replacing the oil ring. The above seven reasons that the professor sums up for us will cause the bearing to overheat; here; work The staff prompts us to check and repair in time; to avoid problems.

The main difference between these two modes is that the 0-10v dimming mode can set the brightness of the light after the person walks, and the pending time of this brightness can also be set. On/off mode, you can only set the time for the lights to turn off after a person walks, but not the brightness (that is, functions 3, 4 cannot be implemented). The 0-10v dimming mode is more intelligent.
Briefly introduce the function of sensor light:
1. Set up daylight threshold: If the ambient light is higher than the set brightness, the sensing function will not be triggered.
2. Set up the hold time: The time for the light to maintain brightness after the person walks away.
3. Set up a stand-by dim level: set the brightness maintained after the person walks
4. Set up stand-by time: After the person walks, the time to maintain low brightness
5. Set up detection area: Set the detection area.
