The FAG 21313-E1-K-TVPB is a high-quality spherical roller bearing manufactured by FAG (part of Schaeffler Group). This bearing features a tapered bore, allowing for easy mounting and dismounting using an adapter sleeve. It is designed to accommodate very heavy radial loads and moderate axial loads in both directions. The 'E1' suffix indicates an optimized internal design for increased load capacity, 'K' denotes a tapered bore (1:12 taper), and 'TVPB' signifies a solid window cage made of glass fiber reinforced polyamide 66, with an outer ring without a lubrication groove or holes. This robust bearing is suitable for applications requiring high reliability and performance under demanding conditions.
