Description
The NJ 309 ECJ is a robust single row cylindrical roller bearing engineered for heavy-duty applications requiring high radial load capacity and reliable performance at elevated speeds. Its NJ design, with two flanges on the outer ring and one on the inner ring, provides axial location of the shaft in one direction, ensuring precise axial guidance where needed.
The separable construction simplifies installation, removal, and interchangeability of components, reducing downtime and improving serviceability. A durable sheet metal cage enhances stability and ensures dependable performance under demanding operating conditions. As part of the SKF Explorer performance class, the NJ 309 ECJ offers optimized load distribution, reduced friction, extended service life, and consistent performance in motors, gearboxes, compressors, and other industrial machinery.
