SKF 1309 ETN9 Self-Aligning Ball Bearing

SKF 1309 ETN9 is a double‑row self‑aligning ball bearing with a cylindrical 45 mm bore, designed to accommodate shaft misalignment in rotating equipment. It measures 100 mm in outer diameter and 25 mm in width, and uses a nylon cage (ETN9) for smooth operation in an open, unsealed configuration. This bearing features no seals or shields, making it well suited for general industrial machinery, conveyors, and gear drives where precise alignment cannot be guaranteed and angular misalignment must be absorbed by the bearing itself. As part of SKF’s 1300 series, the 1309 ETN9 combines misalignment tolerance with a compact footprint, delivering reliable radial load handling in applications where standard 1309 dimensions are used.
