This single row cylindrical roller bearing has a bore diameter of 45.0 mm, an outside diameter of 85.0 mm and a width of 23.0 mm, with a net mass of 0.416 kg. The design features two ribs on the outer ring and one rib on the inner ring (type NJ), functioning as a semi-locating bearing. It is fitted with a TVP2 cage and reinforced E design rollers, giving a limiting speed of 11800 1/min and a reference speed of 5800 1/min. The radial internal clearance falls in group CN (normal), suitable for standard fits without additional play adjustment. The one-rib and two-rib configuration allows axial displacement of the inner ring relative to the outer ring on one side, while providing location on the other, making it suitable for shaft arrangements requiring free axial movement to compensate for thermal expansion. The polymer TVP2 cage guides the rollers with reduced friction and supports operation up to the stated speed limits.
