Loss Combination Needle Roller Bearing Main Factor

What is Needle roller bearings

Needle roller bearings are roller bearings with cylindrical roller, relative to its diameter, the roller is thin and long. This type of roller is called a needle roller. Although has the small section, the bearing still has the high load bearing capacity, the needle roller bearing is equipped with the thin and the long roller, therefore the radial structure is compact, its inside diameter size and the load capacity is the same as other types of bearings, the outer diameter is the smallest, especially suitable for the radial installation size is limited the supporting structure.

Characteristics of Needle roller bearings

Needle roller bearings are equipped with thin and long rollers, so the radial structure is compact, the inside diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, especially suitable for the radial installation size of the limited supporting structure.

Application of Needle roller bearings

Roller needle roller bearing is suitable for printing machinery, forage machinery, agricultural machinery, CNC equipment guide rail roller, conveyor line, etc.

Loss combination needle roller bearing main factor

There are many reasons for the loss of combined needle roller bearings. All the influencing factors in the design and manufacturing process are related to the loss of combined needle roller bearings, which is not easy to distinguish. But in ordinary circumstances, can be roughly from the use of elements and internal elements of two aspects of thinking and analysis.

The use of loss combination needle roller bearings mainly refers to the installation and adjustment, the use of care, maintenance and repair can agree with the technology begged. The installation condition is one of the primary elements in the use of elements. The combined needle bearing often causes the stress state of the whole set of combined needle bearing parts to change due to the improper installation, and the combined needle bearing runs and loses in the abnormal state. According to the combination of needle roller bearing installation, use, maintenance, nursing technology begged, the operation of the combination of needle roller bearing under the load, speed, working temperature, vibration, noise and lubrication conditions stop monitoring and inspection, found abnormal immediately find the cause, stop adjustment, so that it returns to normal. In addition, it is also important to analyze and test the quality of grease and the surrounding medium and atmosphere.

Whether the lubrication is proper also has a great help to the use of combined needle roller bearings. The grease lubricated with grease has both sealing effect. The sealing structure and lubrication equipment are simple, and the grease is easy to supplement.

The cooling effect of oil lubrication is strong, and it can take away dirt and moisture from the combined needle roller bearing. Combination needle roller bearings with oil lubrication lubrication methods include pressure oil supply lubrication, oil injection lubrication, oil mist lubrication and oil and gas lubrication. Pressure oil supply lubrication is the most effective lubrication method for combined needle roller bearing under the normal rotation speed. Oil injection lubrication is the lubricating oil with a certain pressure through the injection nozzle installed on the side of the combination needle roller bearing into the bearing interior to stop lubrication, commonly used in high-speed combination needle roller bearing, or pressure oil supply lubrication can not meet the cooling begged place. Spray lubrication is to spray the monotonous compressed air containing oil mist into the interior of the combined needle roller bearing to stop lubrication. The amount of oil is less, and the cooling effect is very strong due to the effect of air. Both pressure oil supply lubrication and oil injection lubrication need to be equipped with inlet and outlet tubing, lubrication pump, oil storage device, and sometimes lubricating oil cooler. Therefore, the cost is higher, and the common combination needle roller bearing is less used.
