NJ 220 ECM

The NJ 220 ECM Single Row Cylindrical Roller Bearing is an essential component designed to handle demanding industrial applications where high radial load capacity and excellent speed performance are critical. Featuring a separable design with two integral flanges on the outer ring and one on the inner ring, this NJ-type bearing not only facilitates easier mounting and inspection but also allows for axial displacement in one direction. The 'EC' designation signifies an optimized internal geometry with enhanced roller-end/flange contact, which significantly boosts both the axial load-carrying capacity and overall operational stability. Furthermore, the 'M' suffix typically denotes a robust, machined brass cage, which is crucial for high-speed operation and provides superior durability and low friction compared to traditional pressed steel designs, ensuring a longer service life and reliable function.

With precise dimensions of 100mm bore diameter (d), 180mm outer diameter (D), and 34mm width (B), the NJ 220 ECM is a heavy-duty powerhouse in a compact package. Its ability to manage substantial static and dynamic radial loads (up to C_0 305 kN and C 285 kN, for example) while maintaining low vibration makes it a preferred choice for a wide range of machinery. Typical uses include critical applications in gearboxes, large electric motors, traction motors, and heavy industrial pumps and compressors. Choosing this bearing means investing in operational efficiency and minimized downtime, as its robust construction and high-performance capabilities are engineered to withstand the rigorous conditions often found in mining, cement, and material handling sectors.
