The NUP2208 Cylindrical Roller Bearing is a high-performance bearing designed to support heavy radial loads while also accommodating limited axial loads in both directions. Its NUP-type structure features fixed ribs on both sides of the inner ring and a loose rib on the outer ring, combined with a separate loose thrust ring, allowing precise axial positioning.
Manufactured from premium chrome steel and available in stainless steel and special material options, the NUP2208 bearing delivers excellent rigidity, low friction, and stable performance under demanding industrial conditions. It is widely used in gearboxes, motors, and heavy machinery requiring reliable load support and accurate shaft positioning.
With its separable design, the NUP2208 bearing is easy to install, maintain, and inspect, making it ideal for continuous operation in harsh working environments.
