This barrel roller bearing carries radial loads through a single row of barrel-shaped rollers running on a spherical outer raceway, which permits the bearing to accommodate shaft misalignment. Main dimensions follow DIN 635-1: bore diameter 120.0 mm, outside diameter 260.0 mm, width 55.0 mm, net mass 15.1 kg. The limiting speed is 2750.0 1/min, radial internal clearance is CN (Group N), the cage designation is MB, and the bore type is Z. The spherical raceway design allows the bearing to compensate for shaft deflection and housing misalignment without loss of load capacity, making it suitable for applications where shaft or housing alignment cannot be guaranteed with precision. CN internal clearance corresponds to normal operating clearance, suitable for standard fit conditions without additional preload. The MB cage is a machined brass cage, providing stable roller guidance at the stated limiting speed. Bore type Z indicates a cylindrical bore. Lubrication and sealing are not integrated into the bearing and must be provided by the surrounding housing arrangement.
