This single-row cylindrical roller bearing carries two ribs on the outer ring and a smooth (rib-free) inner ring, allowing axial displacement between the rings and making it a non-locating bearing. Bore diameter is 130.0 mm, outside diameter 230.0 mm, width 40.0 mm, and net mass is 7.075 kg. The bearing is fitted with an M1 machined cage and built to the E design, achieving a limiting speed of 5200.0 1/min and a reference speed of 2800.0 1/min. Radial internal clearance is CN (Group N). The floating inner/outer ring arrangement compensates for shaft thermal expansion and axial position changes, so this bearing is suited for one bearing position in a shaft system where axial fixation must be handled elsewhere. Running accuracy is manufactured to P6, giving tighter dimensional and rotational tolerances than standard class, while the CN clearance suits normal fit and temperature conditions. The open design without integrated seals requires external sealing and a separate lubrication supply, either grease or oil, matched to the application's speed and temperature range.
