SKF 1208 ETN9 Self-Aligning Ball Bearing

SKF 1208 ETN9 is a double‑row self‑aligning ball bearing with a cylindrical bore (d = 40 mm, D = 80 mm, B = 18 mm). It is an open, unsealed bearing manufactured from bearing steel to withstand rotation with shaft misalignment. The 1208 ETN9 designation denotes a cylindrical bore self‑aligning configuration, designed to compensate for angular misalignment in rotating equipment. It supports a dynamic load rating of about 19.9 kN and a static rating of around 6.95 kN, placing it in the medium‑load range for light‑ to moderate‑duty machinery. The cylindrical bore and open construction facilitate straightforward mounting and lubrication in compatible housings, making it a common choice when misalignment tolerance is required in conveyors, pumps, and other rotating systems.
