NU 3172 ECMA

The NU 3172 ECMA stands as a robust single row cylindrical roller bearing designed to tackle massive radial forces in demanding environments. With its 360x600x192mm dimensions, this unit features the classic NU-style configuration-two fixed ribs on the outer ring and a smooth, ribless inner ring. This specific setup is essential for machinery where thermal expansion is a factor, as it permits the shaft to move axially within the bearing without restriction. By utilizing a glass fiber reinforced PA66 cage (ECMA), it strikes a perfect balance between high-speed capability and operational quietness, making it a go-to choice for large-scale industrial gearboxes and heavy motors.

Engineered for reliability, the NU 3172 ECMA cylindrical roller bearing offers a massive basic dynamic load rating of 3410 kN, specifically tailored for high-load industrial sectors like mining and power generation. The separable design is a major practical advantage, allowing for the independent mounting of the inner and outer rings, which significantly cuts down on maintenance downtime. Unlike standard bearings, the ECMA series is optimized for improved lubricant flow and reduced heat generation, even when pushing toward its 1500 r/min limiting speed. If your application demands precision alignment and high radial stiffness under extreme stress, this 360mm bore bearing provides the structural integrity needed to prevent premature fatigue.
