This spherical roller bearing accommodates radial loads combined with shaft misalignment thanks to its symmetric roller and raceway geometry. The design features two symmetric outer ribs with a rib washer, a bore diameter of 320.0 mm, outside diameter of 580.0 mm, and width of 150.0 mm. Net mass is 170.5 kg, with a limiting speed of 1410.0 1/min and a reference speed of 850.0 1/min. The bearing is fitted with a machined brass cage (MB1) that withstands higher operating temperatures and centrifugal forces at elevated speeds. Radial internal clearance corresponds to C3 (Group 3), providing extra clearance to compensate for interference fits and thermal expansion during operation. The cylindrical bore (Z bore type) suits direct shaft mounting, and standard relubrication features allow supply of grease during service to maintain the lubricant film under the specified speed and load conditions.
