The HN 1212 RICH is a needle roller bearing designed without an inner ring. This makes it ideal for applications where the shaft can be hardened and precision-ground to serve as the inner raceway. This design offers a highly compact radial cross-section, making it perfectly suited for assemblies with limited space. This particular bearing has no cage, allowing for the maximum number of needle rollers to be installed, which provides a higher load carrying capacity in a smaller space compared to caged designs. It's particularly effective in oscillating movements and situations where substantial radial loads need to be managed within a small envelope. Its dimensions are a 12 mm bore diameter, 18 mm outer diameter, and 12 mm width, with a weight of 0.009 kg. This product is manufactured in China by RICH.
