Description
The NJ 309 ECP is a high-performance single row cylindrical roller bearing designed for substantial radial load capacity and efficient high-speed operation. Its NJ design, featuring two integral flanges on the outer ring and one on the inner ring, allows axial location of the shaft in one direction, providing precise axial guidance where required.
The separable construction simplifies mounting, dismounting, and replacement of components, reducing downtime during maintenance. A lightweight, non-metallic cage minimizes friction, ensures smoother rotation, and extends service life. As part of the SKF Explorer performance class, the NJ 309 ECP offers optimized load distribution, increased reliability, and consistent performance under demanding conditions.
Ideal for gearboxes, motors, compressors, and heavy industrial machinery, this bearing delivers durability, efficiency, and long-lasting operation.
