The NK 110/40 RICH is a robust 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 for heavy 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 110 mm inner diameter (requiring a precision-ground shaft of this diameter as the inner raceway), 130 mm outer diameter, and 40 mm width, with an approximate weight of 0.884 kg. Manufactured in China by RICH.
