NU2238-E-M1A-C3

The NU2238-E-M1A-C3 Cylindrical Roller Bearing is a single-row, high-performance component engineered for demanding industrial applications that require reliable handling of significant radial loads. This bearing features an 'E' reinforced design for increased load carrying capacity, making it a robust choice for heavy-duty machinery, gearboxes, and large electric motors. Its core dimensions are 190mm (Inner Diameter) x 340mm (Outer Diameter) x 92mm (Width). The 'NU' designation indicates the bearing's design, which has two integral flanges on the outer ring and no flanges on the inner ring; this setup allows for axial displacement, positioning the component as an excellent floating bearing solution. This capability is vital for applications where thermal expansion or slight shaft movements need to be accommodated without inducing unwanted stress on the bearing assembly.

Built with precision and durability in mind, the NU2238-E-M1A-C3 incorporates a machined brass cage ('M1A'), which is two-piece and outer ring guided. This robust cage design is highly resistant to wear, especially under high speeds and elevated operating temperatures, ensuring superior reliability and extended service life. Furthermore, the bearing features C3 radial internal clearance, which is greater than normal. This specific clearance is intentionally designed to manage thermal expansion effectively, preventing roller skidding and maintaining smooth operation across a wide temperature range, typically from -30℃ to +150℃. This combination of high-capacity design, a durable brass cage, and optimized internal clearance makes the NU2238-E-M1A-C3 a highly reliable and cost-effective choice for minimizing downtime and maintenance expenses in critical machinery.
