Product Overview: The NJ 211 Cylindrical Roller Bearing
The NJ 211 bearing is a robust and highly efficient component, belonging to our comprehensive NJ Series of Cylindrical Roller Bearings. With precise dimensions of 55mm Bore Diameter, 100mm Outer Diameter, and 21mm Thickness, this bearing is engineered to handle heavy radial loads while also accommodating axial displacement in one direction. Its design features a single rib on the inner ring and two integral ribs on the outer ring, allowing for precise unidirectional axial location of the shaft relative to the housing. The separable components of NJ type bearings facilitate easier mounting and dismounting, making them a preferred choice for various industrial applications where reliability and ease of maintenance are crucial. As a trusted supplier of industrial bearings and mechanical parts, we ensure our NJ 211 bearings meet stringent industry standards for performance and longevity, offering superior reliability in demanding environments.
Key Features of the NJ 211 Bearing
