Product Description
K172110 needle roller bearing K17X21X10
Product Description
Needle roller bearings are cylindrical roller bearings, relative to its diameter, the rollers are thin and long. This roller is called a needle roller. Although the bearing has a small cross-section, the bearing still has a high load bearing capacity, needle roller bearing with a thin and long roller (roller diameter D ≤ 5mm, L / D ≥ 2.5, L for the roller length), so Compact radial structure, its inner diameter and load capacity and other types of bearings the same, the smallest diameter, especially for radial installation of the size of the limited support structure.
According to the use of different occasions, can be used without the inner ring bearing or needle roller and cage components, then match the bearing surface and the surface of the casing hole directly as the bearing inner and outer rolling surface, in order to ensure the load capacity and operating performance With the same ring bearing, shaft or shell hole raceway surface hardness, machining accuracy and surface quality should be similar to the bearing ring raceway. Such bearings can only withstand radial loads.
Classification
1.K, centering needle roller and cage assembly
2. NA, NKI needle roller bearings
RNA, NK type without inner ring needle roller bearings
4. HK-type punching outer ring needle roller bearings
5. BK-type punching outer ring needle roller bearings
Materials
Needle roller material for the GCr15 bearing steel, hardened HRC60-65.
Inside and outside the ring material for the GCr15 bearing steel, hardened HRC61-65.
The cage material is made of high quality mild steel or reinforced nylon.
Application
It is dely used in machine tools, metallurgical machinery, textile machinery and printing machinery and other machinery and equipment, and mechanical design can be more compact and smart.
