Product Overview: NKI 2220 Needle Roller Bearing
The NKI 2220 is a high-precision machined ring needle roller bearing with dimensions of 22x34x20mm. As part of our NKI Series, this bearing includes a solid, machined inner ring, making it suitable for applications where the shaft cannot be hardened and ground. Its compact design and low cross-sectional height allow it to handle high radial loads in space-constrained environments. This makes it a preferred choice for a wide range of industrial machinery requiring robust and reliable performance.
Manufactured to exacting standards from high-quality bearing steel, the NKI 2220 ensures durability and extended service life. The inner and outer rings act as raceways for the needle rollers, providing high rigidity and accurate guidance. This bearing is a key component in our extensive catalog of Needle Roller Bearings, designed to meet the rigorous demands of modern engineering.
