SKF 1212 ETN9 Metric Self Aligning Ball Bearing

SKF 1212 ETN9 is a metric, double-row self-aligning ball bearing from SKF's 1200 series. It has a cylindrical bore of 60 mm, an outer diameter of 110 mm, and a width of 22 mm, delivering stable radial support while compensating for shaft misalignment and deflection. The design features a spherical outer race and a two-row ball arrangement that maintains shaft alignment even when mounting surfaces are not perfectly parallel, reducing alignment sensitivity and promoting smooth operation under moderate radial loads. This bearing is commonly used in machinery where shaft runout or misalignment is possible, such as gearboxes, conveyors, and machine tools, providing reliable service life in standard industrial applications. For correct selection, ensure compatibility with housing tolerances and lubrication requirements, and follow SKF installation and maintenance guidelines to preserve geometry and load-carrying capacity.
