The NU312EJ cylindrical roller bearing is a high-performance, single-row bearing designed to accommodate high radial loads and provide smooth operation. The "NU" designation indicates that the bearing has an inner ring without flanges and an outer ring with two integral flanges. This configuration allows for axial displacement of the inner ring, making it ideal for applications where axial movement or thermal expansion may occur.
The "EJ" suffix signifies that the bearing is constructed from high-quality steel, which enhances its strength, durability, and resistance to wear. The bearing typically features a pressed steel cage that helps to evenly space the rollers, reducing friction and preventing roller skidding during operation. This cage design also contributes to smoother, quieter operation and improved performance at higher speeds.
NU312EJ cylindrical roller bearings are widely used in electric motors, gearboxes, pumps, and various industrial machinery where high radial load capacity and reliable performance are essential. The open design allows for easy lubrication, ensuring efficient operation and longer service life in demanding applications. The robust construction and efficient roller spacing make it a reliable choice for a wide range of applications requiring high load-carrying capacity and durability.
