Bearing raw materials - inner, steel ball or roller processing, outer ring processing, cage (stamping or solid) processing - bearing assembly - bearing finished product

After the NTN bearing is pressed into the bearing, it should rotate flexibly without any sense of blockage. If there is obvious inflexibility in rotation, it indicates that the size of the shaft is too large and the tolerance should be lowered. If the NTN bearing is pressed into the shaft and there is an obvious "sand" feeling when turning it by hand, it may be that the tolerance of the shaft is too large or the roundness of the shaft is not good. Therefore, when controlling the tolerance of the shaft and the bearing chamber, the roundness must also be controlled.

Before the bearing is installed, appropriate measuring tools should be used to check the processing quality of the shaft and seat hole and related parts (such as dimensional accuracy, shape accuracy and surface roughness, etc.) according to the technical requirements on the design drawings.
