This spherical roller bearing has a bore diameter of 90.0 mm, an outside diameter of 190.0 mm, and a width of 64.0 mm, with a net mass of 8.329 kg. The design is E1A with symmetric outer ribs, featuring a tapered bore (K) and a machined cage (M). The limiting speed is 3850.0 1/min, with a reference speed of 3000.0 1/min. The radial internal clearance falls in group C3, allowing for tighter fits and compensating for thermal expansion during operation. The tapered bore (K) simplifies mounting on tapered or adapter-sleeve shaft seatings and permits adjustment of internal clearance during fitting. Relubrication follows the standard feature, requiring periodic grease replenishment through the bearing's lubrication path. The symmetric two-rib outer ring design supports axial guidance on both sides, suiting applications where shaft misalignment must be accommodated without loss of radial load capacity.
