Product Description

The NTN N 309 Cylindrical Roller Bearing is engineered for applications requiring high radial load capacity and precision. Its N-type configuration, with two ribs on the inner ring and no ribs on the outer ring, allows axial displacement of the shaft relative to the housing, making it suitable for systems with thermal expansion or misalignment. Manufactured from premium-quality steel, the N 309 ensures durability, reduced friction, and long service life in industrial environments.
