100 PCSHK1212 Single-row Drawn cup Needle Roller Bearing
⚙️Structural features:
The HK1212 needle roller bearing is a single-row needle roller bearing without an inner ring. The outer ring has open ends and is in a drawn cup type structure. It is made of sheet steel and has a relatively thin wall thickness. The bearing is equipped with multiple thin and long needle rollers. The retaining ring made of sheet steel evenly separates the needle rollers to reduce friction, vibration and noise.
Performance parameters: The basic rated dynamic load is 6.27kN, the basic rated static load is 7.35kN, the fatigue load limit is 0.85kN, the reference speed is 16000r/min, and the limit speed is 18000r/min.
Material and manufacturing: The bearings are made of bearing steel, which has good wear resistance and fatigue strength. The cage is made of sheet steel and has an ordinary tolerance grade.

Due to its compact radial structure and high load-bearing capacity, it is suitable for applications where the radial installation size is limited, such as in gearboxes and transmission shafts of machine tools, automobiles, motorcycles, textile machinery, printing machinery, agricultural machinery, and other related fields.
| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
