SKF 1206 ETN9 Self Aligning Roller Bearing

SKF 1206 ETN9 is a double‑row self‑aligning ball bearing with a cylindrical bore of 30 mm, an outer diameter of 62 mm, and a width of 16 mm, designed to compensate shaft‑to‑housing misalignment in rotary systems. It carries a basic dynamic load rating of 15.6 kN and a basic static load rating of 4.65 kN, making it suitable for light‑ to medium‑duty applications where precise alignment cannot be guaranteed. This bearing features normal radial clearance (CN) and is typically supplied in an open configuration suitable for a 30 mm bore; a C3 version (1206 ETN9/C3) is also available for greater internal clearance. With two rows of balls and bearing steel construction, it's commonly used in small machinery and general‑purpose equipment where misalignment tolerance reduces wear and maintenance, and it offers a reference speed around 24,000 rpm and a limiting speed near 15,000 rpm depending on lubrication and mounting conditions.
