NTA Bearing Thrust Needle Roller Bearing Cage NTA-4052

Selection and control of tolerance for thrust roller bearing chamber: After pressing in the thrust roller bearing, it should rotate flexibly without any obstruction. If there is obvious inflexibility in rotation, it indicates that the size of the shaft is too large and the tolerance needs to be lowered. If there is a noticeable "rustling" feeling when the thrust roller bearing is pressed into the shaft and rotated by hand, it may be due to excessive tolerance or poor roundness of the shaft. So when controlling the tolerance of the shaft and thrust roller bearing chamber, it is also necessary to control the roundness.
Assembly method of thrust roller bearings: As thrust roller bearings are high-precision products, improper assembly can easily cause damage to the grooves of the thrust roller bearings. Causing damage to the thrust roller bearing. The thrust roller bearing should have a dedicated mold during assembly and cannot be knocked randomly. When pressing the shaft, only the small ring can be subjected to force, and when pressing the large ring, only the large ring can be subjected to force. During assembly, it is required to use air pressure or hydraulic pressure. The upper and lower molds should be in a horizontal state during press fitting. If there is any inclination, it will cause damage to the groove of the thrust roller bearing due to force, resulting in a rattling of the thrust roller bearing.
