The NP259742/NP378917 RICH is a high-precision single row tapered roller bearing specifically engineered to handle combined radial and axial loads in compact mechanical environments. With its precise dimensions of 25 mm bore, 51.4 mm outer diameter, and 13.2 mm total width, this bearing is optimized for applications where high load capacity must be achieved within a low-profile assembly.
The internal geometry features tapered rollers and raceways arranged to ensure uniform load distribution. This design significantly reduces friction and heat generation during operation, improving overall rotational efficiency. The separable construction — consisting of the cone (inner ring assembly) and the cup (outer ring) — allows for independent mounting and simplified maintenance, enabling precise adjustment of internal clearance or preload during the installation process.
Manufactured to meet rigorous performance standards, the NP259742/NP378917 RICH provides excellent structural stability. It is built to withstand the stresses of high-torque environments, Ensuring long-term reliability for specialized automotive and industrial power transmission systems.
