Japanese NTN bearings usually consist of inner ring, outer ring, roll body and cage. Usually the inner ring changes with the journal; the outer ring is fixed in the bearing hole of the base or part. The inner and outer rings are made with raceways. When the inner and outer rings rotate relative to each other; the roll body will roll along the raceway. The role of the cage is to evenly separate the roll body along the raceway.
The information of the rolling body and the inner and outer rings should have high hardness and touch fatigue strength, excellent wear resistance and impact toughness. It is usually made of chrome-containing alloy steel; after heat treatment, the hardness can reach HRC61~65; the surface of the work must be ground. And polishing. The cage is usually made of low carbon steel stamping; high speed bearings are mostly made of non-ferrous metal or plastic cage.
Compared with sliding bearings; NTN imported bearings have conflicting resistance. é¸²æ§Šç°Ÿ (12) çŸ¢ ( (4) è ¡è™®æ„«é¸µ è¯¨ã‚» æ‰” æ‰” æ‰” æ‰” æ‰” æ‰” æ‰” æ‰” æ‰” Ï„ Ï„ å®ƒ å®ƒ å®ƒ å®ƒ å®ƒ å®ƒ å®ƒ å®ƒ å®ƒ å®ƒ å®ƒ å®ƒ å®ƒ å®ƒ å®ƒ Ï„ Ï„ Ï„ Ï„ Ï„ Presenting noise; the sliding life of the working life is not as good as the liquid conflict. Because the NTN bearing is now standardized; and the bearing factory produces it in large quantities; therefore; the user's mission is mainly to understand the specification and correct selection.
Different shapes of the roll body; according to the roll shape NTN imported bearings can be divided into ball bearings and roller bearings. Rollers are divided into long cylindrical rollers, short cylindrical rollers, spiral rollers, tapered rollers, spherical rollers And needle roller, etc.
