The FAG 3204-BD-XL-2HRS-TVH-C3 is a high-quality double row angular contact ball bearing designed for applications requiring high rigidity and precision. It features a 20mm bore diameter, 52mm outer diameter, and 20.6mm width. The '2HRS' designation indicates seals on both sides, providing protection against contaminants and retaining lubricant. The 'TVH' signifies a solid window cage made of glass fibre reinforced polyamide, offering good sliding properties and reduced noise. 'C3' indicates a larger than normal radial internal clearance, suitable for applications with higher operating temperatures or where shaft expansion is expected. This bearing is part of the XL series, denoting optimized internal geometry for enhanced performance.
