NU238-E-M1A

The NU238-E-M1A is a premium-grade, single-row cylindrical roller bearing engineered for demanding industrial environments that require superior radial load capacity and high-speed stability. Featuring an "E" design for optimized internal geometry, this unit provides a significantly higher load rating than standard versions, ensuring extended service life even under peak stress. Its defining characteristic is the M1A solid brass cage, which is two-piece and outer-ring guided. This robust cage construction minimizes friction and heat buildup, making it an excellent choice for heavy-duty gearboxes, large electric motors, and high-performance pumps where vibration and impact loads are common.

With a precision-ground 190mm bore and a 340mm outside diameter, the NU238-E-M1A offers exceptional rigidity and dimensional accuracy. As a non-locating bearing of the NU design, it features two integral ribs on the outer ring and a smooth inner ring, allowing for axial displacement of the shaft relative to the housing in both directions. This flexibility is critical for accommodating thermal expansion in long shafts. The separable design further simplifies the installation process, allowing the inner and outer rings to be mounted independently, which reduces the risk of damage during assembly and streamlines routine maintenance workflows in complex machinery.
