The FAG 23228-E1A-XL-K-M-C4 is a high-performance spherical roller bearing manufactured by INA-FAG (Schaeffler Group). This bearing features a 140 mm bore diameter, 250 mm outer diameter, and 88 mm width. It is designed with a tapered bore (K) for mounting with adapter or withdrawal sleeves, a solid brass cage (M), and an increased radial internal clearance (C4), making it suitable for applications with high temperatures or where shaft expansion is expected. The 'E1A' and 'XL' designations indicate an optimized internal design for higher load ratings. This bearing is capable of accommodating heavy radial loads and axial loads in both directions, as well as misalignment.
