The NACHI NJ306EG is a single row cylindrical roller bearing designed for high radial load capacity and reliable performance in demanding applications. It features a 30 mm bore, 72 mm outer diameter, and 19 mm width, with a robust steel alloy construction for durability. This bearing offers a dynamic load rating of 53,000 N and a static load rating of 50,000 N, supporting high-speed operation up to 8,500 rpm with grease lubrication and 10,000 rpm with oil. Its design allows for axial displacement of the inner ring, making it ideal for support applications where shaft expansion or contraction occurs. The NJ306EG is known for its precision, long service life, and suitability for industrial machinery, automotive systems, and heavy equipment.
