This single row cylindrical roller bearing separates radial load carrying from axial guidance, since its NU design places two ribs on the outer ring and leaves the inner ring smooth, allowing free axial displacement between rings. Bore diameter is 190.0 mm, outside diameter 340.0 mm, width 55.0 mm, net mass 21.62 kg. Limiting speed is 3050.0 1/min, reference speed 1720.0 1/min, and internal radial clearance corresponds to CN (Group N). The cage is executed in M1, and the E design improves load distribution across the roller set. Being a non-locating bearing, it accommodates axial shaft expansion without introducing constraint forces, making it suitable as the floating bearing in a shaft arrangement. Running accuracy in P6 supports precise radial guidance, while the CN clearance group and M1 cage provide stable roller guidance and consistent operation at the stated speed limits.
