The NJ309 MC3 cylindrical roller bearing is engineered for high radial load capacity and reliable performance in demanding industrial applications. With a bore diameter of 45 mm, outer diameter of 100 mm, and width of 25 mm, this single-row bearing features a machined brass cage for enhanced durability and smooth operation. The C3 internal clearance allows for greater thermal expansion, making it suitable for high-speed environments. Its design includes one flange on the inner ring and two on the outer ring, enabling axial displacement in one direction while maintaining precise alignment. Ideal for machinery requiring robust, long-lasting rotational support, the NJ309 MC3 combines precision engineering with excellent load handling and low friction characteristics.
