This spherical roller bearing carries a two-row roller set on a symmetric outer ring with two ribs, bore diameter 70.0 mm, outside diameter 150.0 mm, and width 51.0 mm. The design is designated E1A, with a machined brass cage (M) and a C3 internal clearance (Group 3), giving a looser-than-normal fit between rolling elements and raceways. Limiting speed is rated at 4800 1/min, with a reference speed of 3700 1/min; mass is 4.266 kg. The spherical outer raceway allows the bearing to accommodate shaft misalignment and deflection without binding, which is the main reason to select this double-row design over a single-row type. The C3 clearance compensates for the temperature rise expected under load, maintaining proper internal fit once the bearing reaches operating temperature. The M cage design supports higher speeds and offers stable guidance of the rollers under combined radial and axial load. Dimensional and constructional equivalents include NSK 22314CAME4C3, RHP 22314EMW33C3, SNR 22314EB33MJ30, and SNR 22314EMW33C3.
