This spherical roller bearing accommodates radial loads together with axial loads acting in either direction while tolerating shaft misalignment. Main dimensions follow DIN 635-2: bore diameter 150.0 mm, outside diameter 270.0 mm, width 96.0 mm, mass 22.883 kg. The bore is tapered, taper 1:12 (bore type K), allowing mounting on a tapered seat or with an adapter sleeve and enabling adjustment of the internal clearance during fitting. Limiting speed is 2400 1/min, reference speed 1400 1/min. Internal design is E1A, cage is machined brass (M), radial internal clearance is C3 (Group 3), greater than normal clearance. The C3 clearance compensates for interference fit resulting from mounting on the tapered bore and for thermal expansion during operation, so it should be taken into account when setting the axial drive-up on the taper. The E1A internal design increases roller and raceway contact capacity within the same envelope dimensions. The bearing has no integrated seals, so relubrication and external sealing must be arranged separately; relubrication feature is standard.
