SKF 1304ETN9 Self-Aligning Ball Bearing is a double‑row, self‑aligning bearing designed to accommodate shaft misalignment in light machinery. It features a cylindrical 20 mm bore, a 52 mm outer diameter, and a 15 mm width with an open closure for straightforward lubrication. The ETN9 variant uses a glass fiber reinforced polyamide PA66 cage (TN9), delivering durable cage guidance for the balls while keeping weight down. This bearing is suited for light machinery and general‑purpose applications where reliable self‑alignment and smooth rotation are required.
