The B-148 RICH is a robust needle roller bearing without an inner ring, designed for applications where the shaft can be hardened and precision-ground to serve as the inner raceway. This design offers a compact radial cross-section, making it highly suitable for installations with limited space. This particular bearing operates without a cage, utilizing a full complement of needle rollers to maximize load carrying capacity. It is exceptionally effective in oscillating movements and situations requiring high radial load management within a confined envelope. Its dimensions are a 22.22 mm bore diameter, 28.58 mm outer diameter, and 12.7 mm width. It has a weight of 0.025 kg. This product is manufactured in China by RICH.
