NU 306 EM1 FAG Cylindrical Roller Bearing 30x72x19

Single Row Cylindrical Roller Bearing for High Radial Loads

NU Design for Axial Displacement Compensation

EM1 Cage for Stable Industrial Operation

Main Description

NU 306 EM1 FAG is a high-quality single row cylindrical roller bearing with dimensions 30x72x19, designed for demanding industrial applications where high radial load capacity and long service life are required. Compared to a standard ball bearing, the cylindrical roller design offers significantly higher radial load capability, making it suitable for continuous and heavy-duty operation.

The NU design features no flanges on the inner ring, allowing free axial displacement of the shaft relative to the bearing housing. This design effectively compensates for thermal expansion and shaft elongation, reducing internal stresses in the system. Axial location is typically provided by another bearing unit within the assembly, ensuring stable and predictable operation.

The EM1 brass cage provides robust roller guidance, excellent lubrication conditions, and resistance to dynamic loads. This cage design supports smooth rotation at higher operating speeds and contributes to high durability and consistent performance over long operating cycles.

NU 306 EM1 FAG cylindrical roller bearing is widely used in electric motors, gearboxes, pumps, industrial drives, and production machinery. It is a proven solution for OEM manufacturers, maintenance departments, and industrial service providers who require components with clearly defined technical parameters and reliable performance in harsh operating conditions.

Proper selection and installation of this bearing help reduce downtime, protect shafts and housings, and improve overall machine efficiency in industrial environments.
