The FAG 21309-E1-XL-C3 is a high-quality spherical roller bearing designed for robust performance in demanding industrial and agricultural applications. Featuring a 45 mm bore, 100 mm outer diameter, and 25 mm width, this bearing is engineered to accommodate heavy radial and axial loads. The 'E1' designation indicates an optimized internal design for increased load capacity, while 'XL' signifies an extra-long service life. The 'C3' radial internal clearance is greater than normal, suitable for applications with high temperatures or where shaft expansion is expected, preventing premature wear and ensuring smooth operation. Manufactured by FAG, a brand of Schaeffler, it ensures reliability and durability.
