This spherical roller bearing carries a tapered bore (bore type K) with a 1:12 taper, allowing mounting on an adapter or withdrawal sleeve and adjustment of internal clearance during fitting. The design (BEA) features two symmetric outer ribs with a rib washer, and the bearing uses a machined brass cage (MB1). Bore diameter is 340.0 mm, outside diameter 580.0 mm, width 190.0 mm, and net mass is 199.2 kg. The limiting speed is 1090.0 1/min, with a reference speed of 600.0 1/min. The spherical shape of the double row of rollers gives self-aligning capability, compensating for shaft deflection and housing misalignment without loss of load capacity. The tapered bore construction lets the fitter set the operating clearance to suit the application during installation, which is relevant where a defined internal clearance class is required after mounting. Relubrication is standard, meaning the bearing is designed for periodic relubrication through a lubrication feature rather than being sealed for life.
