NNU4136-S-M

The NNU4136-S-M is a high-performance double-row cylindrical roller bearing engineered for applications that demand extreme radial rigidity and precision. Featuring a solid brass cage (M) and a lubrication groove with holes in the outer ring (S), this bearing is designed to handle heavy radial loads while maintaining stability at high operational speeds. Its double-row configuration provides a significantly larger contact surface compared to single-row variants, making it an ideal choice for the main spindles of machine tools and heavy-duty industrial gearboxes where minimal deflection is critical for accuracy.

Built to withstand rigorous industrial environments, the NNU4136-S-M offers a separable design that simplifies mounting and dismounting during maintenance. The use of a machined brass cage ensures superior guiding of the rollers, reducing friction and heat generation even under intense pressure. With its high load-carrying capacity and "Super Precision" rating, this bearing supports smooth, vibration-free rotation. Whether used in metallurgy, large-scale printing presses, or precision engineering equipment, the NNU4136-S-M delivers a long service life and reliable operational safety across a wide temperature range.
