SKF 22311EK Spherical Roller Bearing

SKF 22311EK is a double‑row spherical roller bearing with a 55 mm bore, 120 mm outer diameter, and 43 mm width, configured with a tapered bore at 1:12 for mounting on a shaft or via an adapter sleeve. The EK suffix signals a modernized inner ring and roller design within the SKF family, and some listings include EK/C3 variants with increased radial clearance as well as adapter‑bore versions such as EK/VA759. Classified as an SKF Explorer bearing, it is engineered for high performance in demanding setups. With its spherical geometry, the bearing is designed to carry heavy radial loads while accommodating misalignment, making it suitable for applications such as industrial gearboxes, conveyors, and other power‑transmission machinery where precise alignment is challenging.
