This spherical roller bearing accommodates radial loads together with angular misalignment between shaft and housing, using a symmetric roller set with two outer ribs and a rib washer in the BEA design. Bore diameter is 480.0 mm, outside diameter 700.0 mm, and width 218.0 mm, giving the mounting envelope for shaft and housing seats. Mass netto is 279.5 kg, relevant for handling and lifting during installation. Limiting speed is rated at 770.0 1/min, with a reference speed of 385.0 1/min for thermal running conditions. The MB1 cage is a machined brass cage, suited to the operating speeds given above. Radial internal clearance falls in the CN (Group N) range, the standard clearance class for this bore size, which should be checked against the actual mounting fit and any temperature differential expected in operation. Bore type Z indicates a cylindrical bore version of this size. Relubrication feature is standard, meaning the bearing is designed for periodic relubrication through a conventional arrangement rather than a sealed-for-life configuration.
