Description
The NU 305 ECJ is a high-performance single row cylindrical roller bearing designed for demanding industrial applications requiring high radial load capacity and high-speed operation. Its NU design, featuring two flanges on the outer ring and no flanges on the inner ring, allows axial displacement in both directions, accommodating thermal expansion and shaft movement without compromising performance.
The bearing’s separable construction simplifies installation, dismounting, and component replacement. A durable sheet metal cage reduces friction and wear, promoting smooth operation and extended service life. As part of the SKF Explorer performance class, the NU 305 ECJ provides reliable, high-efficiency performance in demanding industrial conditions.
This bearing is ideally suited for motors, gearboxes, pumps, and other machinery where low-maintenance, dependable rotational performance is essential.
