This single row cylindrical roller bearing carries a full complement roller set, giving increased contact area within the 670.0 mm bore and 820.0 mm outside diameter envelope, with a width of 69.0 mm. The outer ring has 1 rib and the inner ring has 2 ribs, forming a semi-locating arrangement that guides the rollers while allowing axial displacement on one side. Net mass is 72.0 kg. Limiting speed is rated at 405.0 1/min, with a reference speed of 242.0 1/min. Radial internal clearance is in the CN (Group N) range, suited to standard fits without preload. The E design indicates a reinforced roller and cage configuration for the full complement set. As a semi-locating bearing, it supports radial loads while permitting axial movement of the shaft relative to the housing on the non-located side, useful where thermal expansion or shaft positioning needs to be accommodated at this bore size.
