SKF 1211EKTN9 Self Aligning Ball Bearing

SKF 1211EKTN9 is a two‑row self‑aligning ball bearing with a tapered bore designed to tolerate shaft misalignment while carrying radial and light axial loads. It has a 55 mm bore, 100 mm outer diameter, and 21 mm width, with a 1:12 tapered bore for mounting on a matching shaft or adapter sleeve. This open (unsealed) bearing is made from bearing steel and features radial internal clearance CN. It provides a basic dynamic load rating of 27.6 kN and a basic static load rating of 10.6 kN, with a reference speed of 14,000 r/min and a limiting speed of 9,000 r/min. The 1211EKTN9 is designed for installations where shaft–housing misalignment must be accommodated while maintaining smooth rotation.
