The NK30/20 RICH is a compact needle roller bearing designed without an inner ring, intended for applications where the shaft serves as the inner raceway. This design provides a space-efficient and potentially cost-effective bearing solution. Engineered to support high radial loads, the bearing utilizes needle rollers, providing a large contact area for efficient load distribution. It features a steel cage to ensure precise roller guidance and spacing, promoting smooth and reliable operation. The dimensions of this bearing are 30 mm inner diameter (requiring a precision-ground shaft of this diameter as the inner raceway), 40 mm outer diameter, and 20 mm width, with a light approximate weight of 0.07 kg. Manufactured in China by RICH.
