The importance and method of NSK bearing lubrication

NSK bearings in normal operation, the original import NSK bearing lubrication is an important part of NSK bearing maintenance and maintenance. Today, Shanghai Hong Yu Xiao Li described for you how to lubricate NSK bearings.


1. Smooth drop of NSK bearing

Dripping oil is smooth and suitable for the need to quantify the supply of smooth oil to NSK bearing components. It is advisable to dispense one drop every 3-8 seconds individually. Excessive oil volume will cause the bearing temperature to increase.

2. The oil bath of NSK bearings is smooth

The smoothness of the oil bath is the most common smoothing method in NSK bearings and is suitable for the smoothness of low and medium speed bearings. The NSK bearing is partially immersed in the groove, the smooth oil is carried by the rotating bearing part, and then the oil surface flowing back to the oil groove should be slightly lower than the center of the lowest rolling element.


3. Smooth NSK bearing circulation oil

The oil pump is used to send the filtered oil to the NSK bearing parts, and the smooth oil after the bearing is used for filtering and cooling. Because the circulating oil can take away a certain amount of heat to cool the bearing, this method is actually used for bearing components with higher rotational speed.

4. Radiating smoothness of NSK bearings

The oil pump is used to shoot low pressure oil through the nozzle into the NSK bearing, and the oil injected into the bearing flows into the oil tank through the other end of the bearing. When the bearing rotates at high speed, the rolling element and the maintenance frame also cause the surrounding air to cause airflow at a reasonably high rotation speed. It is difficult to send the smooth oil to the bearing in a single smooth manner. At this time, the smooth oil must be sprayed in a manner of low pressure radiation. To the bearing, the position of the nozzle should be placed between the inner ring and the center of the holding frame.

5. Smooth NSK Bearing Spray

With dry shrink air through the sprayer and smooth oil mixed to cause oil mist, radiation NSK bearings, air flow can effectively reduce the temperature of the bearing and can avoid intrusion of impurities. This method is suitable for the smoothness of high-speed, low-temperature bearing components.

Basic Peristaltic Pump

The main factors that need to be considered when using a basic Peristaltic Pump include the compatibility of the liquid with the Peristaltic Pump Tubing used, the trade-off between flow rate and pulse rate(roller number), Each rotation will dose equal liquid volume which ensures the flow accuracy. and the roller number decides the pulsation of the liquid, if you need a low pulsation liquid delivery, pls choose the multiple rollers to pump head or work with the Pulsation damper.
The basic peristaltic pump with a simple display and easy knob control, which can meet the liquid constant transfer industrial cases. For example: food/cosmetic/beverage/checmical additive feeding. transfer the liquid from a big tank to the small tank, liquid circulation..etc.
