Product Overview: The NK 1820 Needle Roller Bearing
The NK 1820 is a high-capacity machined ring needle roller bearing, precision-engineered for applications requiring a compact and rigid bearing arrangement. With key dimensions of 18mm Bore Diameter, 26mm Outer Diameter, and 20mm Thickness, this bearing offers a remarkably low cross-sectional height. As part of our NK Series, it is designed without an inner ring, which allows the shaft itself to serve as the raceway. This design is ideal for space-constrained applications where a hardened and ground shaft can be utilized, providing a cost-effective and efficient solution. The robust machined outer ring ensures high rigidity and reliable performance under heavy radial loads.
As a specialist in industrial components, we offer a comprehensive selection of Needle Roller Bearings. The NK 1820 is an excellent choice for machinery where high load-carrying capacity and minimal space are critical design factors.
