The NK30/30 RICH is a needle roller bearing designed without an inner ring, intended for applications where the shaft can serve as the inner raceway. This design allows for a more compact bearing arrangement and can be advantageous in certain space-constrained applications. The bearing is engineered to support high radial loads, with the needle rollers providing a large contact area for effective load distribution. It features a steel cage that ensures precise guidance and spacing of the rollers, facilitating smooth and reliable operation. The dimensions of this bearing are 30 mm inner diameter (requires a precision-ground shaft of this diameter as the inner raceway), 40 mm outer diameter, and 30 mm width, with an approximate weight of 0.105 kg. Manufactured in China by RICH.
