Loose Needle Rollers

Loose needle roller bearings are equipped with thin and long rollers (the length of the roller is 3 to 10 times the diameter, and the diameter is generally not greater than 5mm), so the radial structure is compact. The diameter and load capacity of loose needle roller bearings are similar to other types. When the bearings are the same, the outer diameter is the smallest, which is especially suitable for supporting structures with limited radial installation dimensions.

Loose needle roller bearings should be combined with bearing rings and applications according to different applications. Needle roller bearings are bearing units that combine radial needle roller bearings and thrust bearing components.Comparison of loose needle roller bearings:

1. The coefficient of friction of loose needle roller bearings is smaller than that of sliding bearings, and the transmission efficiency is high. The friction coefficient of general sliding bearings is 0.08-0.12, while the friction coefficient of rolling bearings is only 0.001-0.005;

2. The loose needle roller bearings have been standardized, serialized and generalized, suitable for mass production and supply, and easy to use and maintain;
3. Loose needle roller bearings are made of bearing steel and are heat treated. Therefore, rolling bearings not only have high mechanical properties and long service life, but also can save expensive non-ferrous metals used in the manufacture of sliding bearings;
4. The internal clearance of loose needle roller bearings is small, and the machining accuracy of each part is high, so the running accuracy is high. At the same time, the rigidity of the bearing can be increased by pre-loading. This is very important for precision machinery;
5. Some loose needle roller bearings can support radial and axial loads at the same time, so the structure of the bearing support can be simplified;
6. Because loose needle roller bearings have high transmission efficiency and less heat generation, the consumption of lubricating oil can be reduced, and lubrication and maintenance are relatively easy;
7. Loose needle roller bearings can be easily applied to any axis in space.
