This cylindrical roller bearing carries a full complement roller set in a single row, with a bore diameter of 70.0 mm, outside diameter of 125.0 mm, and width of 31.0 mm. The outer ring has 1 rib and the inner ring has 2 ribs, giving a semi-locating design of type SL18. Net mass is 1.605 kg, with a limiting speed of 3450 1/min and a reference speed of 2340 1/min. The full complement roller arrangement increases the number of rolling elements in contact, raising radial load capacity within the given dimensional envelope, while the semi-locating configuration allows axial guidance in one direction combined with limited free axial displacement. Radial internal clearance is in group CN, suitable for standard fit and operating conditions. The design designation A indicates the specific rib and cage configuration of this variant, matching the standard bore and outside diameter tolerances for this bearing series.
