On the difference between tapered roller bearing and needle roller bearing? Next, the structure, type, working principle, material, application and other aspects will be introduced

difference:

cylindrical roller bearings are precision bearings. The precisely sorted rollers are guided by the retaining edge of the shaft ring. They are composed of cages, rollers and guide shaft rings, and can be separated from another bearing ring. They are separable bearings. The bearing is easy to install and disassemble, especially when the inner and outer rings are required to be interference fit with the shaft and shell, so the equipment is also engraved with the symbol of the spacecraft, which shows its advantages; This kind of bearing is generally only used for live ammunition with radial load gun, and only the single row bearing with retaining edges on the inner and outer rings can be used with small steady axial load or large intermittent axial load; Compared with other bearings with the same overall dimensions, this bearing has the characteristics of high load, low noise and high speed, and is very suitable for various precision machinery and mining rolling mill machinery. However, the shafts, rolling elements and other relevant parts matched with such bearings need to be precision machined

needle roller bearings (NK, nks, rna49, rna48, NKL, nkls, NA49, na48, rna69, rna49... RS, rna49..2rs, na49..Rs, na49..2rs, RNAO, NAO) have compact structure, small radial dimension and large load capacity. 7 The preparation and utilization technology of new electrical, microelectronic and optoelectronic materials bears a large radial load. This type of bearing has a variety of structures and size series. The assembled G2 grade needle roller has a diameter change of less than 2um in the grouped batch. Except for the fully loaded needle roller bearing, high-performance cage is adopted, which can correctly guide the parallel axis of the needle roller

different structures, different types, different bearing directions, different speeds, different loads, different materials, different applications, etc.

fundamental differences: the rolling element of tapered roller bearing is a tapered roller; The rolling element of the needle bearing is a needle roller

the above fundamental differences determine that the structure of the tapered roller bearing is larger than that of the needle roller bearing. The tapered roller can bear the axial force in addition to the radial force, while the needle roller bearing can only bear the radial force

tapered roller bearings are divided into single row, double row and multi row, which are applied to different environments and occasions respectively

spring is a frequently used part in our daily life and work. The working speed of tapered roller bearing is higher than that of needle roller bearing

tapered roller bearings generally use high-quality bearing steel and special steel; The thin-wall needle roller bearing is made of steel plate

needle roller bearing is composed of thin and long needle roller and cage. Cylindrical roller bearing. It is composed of cylinder and roller. The column is thicker than the needle, also known as the thick needle

although there are differences between the two types of bearings in all aspects, they are consistent in the purpose of use, both for improving efficiency and reducing costs
