SKF 1206 EKTN9 C3 Self-Aligning Ball Bearing

SKF 1206 EKTN9/C3 Self-Aligning Ball Bearing is a double-row, self-aligning unit that uses a common spherical outer race to accommodate shaft misalignment and housing mounting errors. In the 1206 size, it has a 12 mm bore, 62 mm outer diameter, and 16 mm width, with a tapered bore of 1:12 designed for mounting with an adapter sleeve. The “C3” radial clearance designation indicates a larger-than-normal internal clearance, which helps the bearing tolerate misalignment and thermal growth during operation. This bearing distributes loads across two rows of balls for improved load capacity and smoother rotation, making it a common choice for electric motors, gearboxes, conveyors, pumps, and other industrial equipment where precise alignment cannot be guaranteed. The TN9 designation in SKF part codes signals the tapered-bore configuration, while the overall construction—two rows of balls in a spherical outer race—provides robust performance under misalignment, vibration, and varying speeds. When replacing, verify the exact SKF SKU matches the 12 x 62 x 16 mm dimensions and ensure compatibility with your adapter sleeve and mounting housing.
