INA thrust needle roller bearings are made up of raceway rings and needle roller and cage assemblies; they can be combined with thin stamped raceways (W) or thickened raceway rings (WS). The separate bearing is an integral bearing consisting of a finely stamped raceway ring and a needle roller and cage assembly. It can accept one-way axial load of this type of bearing. It takes up space. Muttering, smashing, smashing, smashing, smashing, smashing, smashing.
Tapered Roller Bearings This type of bearing is equipped with a truncated roller; the roller is guided by the large rib of the inner ring. The poles of the conical surfaces of the inner ring raceway surface, the outer ring raceway surface and the roller tumbling plane are depicted. One point on the middle line of the bearing. Single row bearings can accept radial load and one-way axial load; double row bearings can accept radial load and bidirectional axial load; suitable for receiving heavy load and impact load.
Cylindrical roller bearings are different according to the number of rows of rolling mills; cylindrical roller bearings can be divided into single row, double row and multi row cylindrical roller bearings. The more commonly used ones are single row cylindrical roller bearings with cages. In addition; there are other types of cylindrical roller bearings such as single or double row full complement rollers.
Single row cylindrical roller bearings are classified into N type, NU type, NJ type, NF type and NUP type according to the different ferrule ribs. Cylindrical roller bearings can receive large radial load; according to the layout of the ferrule ribs It also accepts a certain one-way or two-way axial load. NN type and NNU double row cylindrical roller bearings have a compact layout; strong rigidity; large bearing capacity; deformation after loading. Kamakura fashion noisy С.FC Four-row cylindrical roller bearings of type FCD and FCDP can accept large radial loads; they are mostly used in heavy machinery such as rolling mills.
INA Spherical Roller Bearings This type of bearing is equipped with a spherical roller between the outer race of the spherical raceway and the inner race of the double raceway; it is different according to the internal layout; it is divided into four types: R, RH, RHA and SR. Because the outer ring The middle of the arc of the raceway is common with the middle of the bearing; it has a self-aligning function; therefore, it can actively adjust the axial misalignment caused by the deflection of the shaft or the casing or the different core. Acceptable radial load and bidirectional axial load. Especially The radial load can be large; it is suitable for accepting heavy load and impact load. The tapered hole bearing can be assembled and disassembled on the shaft through the use of fasteners or withdrawal sleeves. Spherical roller bearings can accept large radial loads; they can also accept a certain axial load. The outer ring raceways of this type of bearings are spherical in shape; therefore, they have a aligning function; when the shaft is subjected to bending or skewing, The middle line of the inner ring and the middle line of the outer ring are not inclined more than 1°~2. 5°; the bearing can still work.
INA thrust roller bearing thrust roller bearings include thrust spherical roller bearings, thrust cylindrical roller bearings and thrust tapered roller bearings. Thrust spherical roller bearings can accept axial and radial loads together; Beyond the axial load of 55%. Another important feature of this type of bearing is its active centering function; thus it is not sensitive to different degrees of heart and shaft deflection. Only load P and P. Do not exceed 0. 05C; and the shaft ring rotates; the bearing promises a certain size of the centering angle. The small value is suitable for large bearings; and the load adjustment angle will be reduced when the load increases.
