NADELLA - 6NBF817YJ086B

Details

These bearing is a high-precision, military-grade double-row airframe control needle roller bearing. This heavy-duty component is engineered for extreme structural and mechanical loads in aerospace, defense, and specialized industrial track systems. The bearing is fundamentally a track roller variant designed for oscillating or slow-rotation applications under intense pressure. Unlike standard commercial bearings, it features a highly robust, thick-walled outer ring designed to roll directly on tracks, cams, or guide rails without bending or fracturing. It utilizes two parallel rows of needle rollers housed without a cage (full-complement design), maximizing the internal contact surface area to handle massive radial and shock loads. It is engineered with a passivated or plated finish to survive harsh environmental exposure. Applications : Packaging & Textile Machinery, Material Handling Equipment, Robotic Joints & Arm Pivots, Marine & Subsea Infrastructure. YJ = Precision Clearance & Seal Specification, B= Factory Lubricant & Surface Finishing Variant.
