This single row cylindrical roller bearing (NU315-E-XL-M1-C3) has a bore of 75.0 mm, outside diameter of 160.0 mm, and width of 37.0 mm, with a net mass of 3.69 kg. The outer ring carries two ribs while the inner ring is smooth (type NU), making it a non-locating bearing that allows axial displacement between inner and outer ring. It runs in P6 accuracy class, with a limiting speed of 7600 1/min and a reference speed of 4150 1/min. The cage is designated M1, and the E design provides increased roller load rating. The smooth inner ring geometry allows the bearing to accommodate axial shaft expansion without additional axial load, making it suitable as a free-end support in a bearing arrangement. Radial internal clearance C3 (Group 3) provides additional clearance to compensate for thermal expansion during operation, while the M1 cage supports stable roller guidance at the stated speed range. Running accuracy in P6 permits use where tighter rotational precision is required than with standard tolerance class.
