Description
The NU 304 ECP is a high-precision single row cylindrical roller bearing engineered to handle substantial radial loads while maintaining high-speed performance. Its NU design, featuring two flanges on the outer ring and none on the inner ring, allows for axial displacement in both directions, accommodating thermal expansion or shaft movement without compromising efficiency.
The bearing’s separable construction simplifies mounting, dismounting, and component replacement, while its non-metallic cage reduces friction and wear, promoting smooth operation and extended service life. As part of the SKF Explorer performance class, the NU 304 ECP delivers enhanced reliability and performance under demanding industrial conditions.
This bearing is ideally suited for electric motors, gearboxes, pumps, and other machinery where efficient, low-maintenance rotational performance is critical.
