This cylindrical roller bearing is built as a single-row, full complement roller set (design TB), with one rib on the outer ring and two ribs on the inner ring, giving it a semi-locating function within the shaft arrangement. Bore diameter is 670.0 mm, outside diameter 820.0 mm, and width 69.0 mm — dimensions to be matched against the housing and shaft seat on the technical drawing. Net mass is 72.0 kg, relevant for handling during mounting. Limiting speed is rated at 405.0 1/min, with a reference speed of 242.0 1/min. The full complement roller arrangement increases the number of rolling elements in contact, which suits applications where radial load capacity is prioritized over high-speed operation, consistent with the limiting and reference speed values given. Radial internal clearance is C3 (Group 3), providing a larger internal clearance than standard, which allows for thermal expansion and shaft deflection during operation. As a semi-locating bearing, it permits axial displacement in one direction while guiding the shaft radially, which must be factored into the shaft and housing fit selection.
