NATR Series

NATR series needle roller bearings are high-performance rolling bearings designed to withstand radial loads. They use a series of small diameter rollers to provide excellent load carrying capacity and stiffness in a small space. The NATR series is characterized by the solid structure of both the inner and outer rings, which has good lateral load resistance and is suitable for high speed and high load conditions. These bearings are widely used in automobiles, machinery and equipment, industrial automation and other fields. The design of NATR series bearings optimizes lubrication performance and temperature control, allowing them to maintain stable performance in various working environments.
