The NK43/30 RICH is a needle roller bearing designed without an inner ring, intended for applications where the shaft serves as the inner raceway. This configuration allows for a more compact and potentially cost-effective bearing solution. Engineered to support high radial loads, the bearing utilizes needle rollers that provide a large contact area for efficient load distribution. It incorporates a steel cage to ensure precise roller guidance and spacing, promoting smooth and reliable operation. The dimensions of this bearing are 43 mm inner diameter (requiring a precision-ground shaft of this diameter as the inner raceway), 53 mm outer diameter, and 30 mm width, with an approximate weight of 0.144 kg. Manufactured in China by RICH.
