23256-BEA-XL-MB1

The 23256-BEA-XL-MB1 is a high-performance FAG spherical roller bearing engineered for the most demanding industrial environments. Featuring a 280mm bore, 500mm outside diameter, and a substantial 176mm width, this unit belongs to the specialized X-life (XL) series, which provides significantly higher basic dynamic load ratings and extended service life compared to standard designs. The internal geometry is optimized for maximum surface contact, ensuring it handles massive radial loads while simultaneously supporting axial forces in both directions. Its double-row, self-aligning construction allows it to compensate for shaft deflections and mounting inaccuracies, making it a critical component for heavy-duty machinery.

Designed for durability and operational stability, the 23256-BEA-XL-MB1 utilizes a solid brass cage (MB1) that is guided on the inner ring. This robust cage design is particularly effective in high-vibration applications or where high accelerations are present, preventing roller skewing and reducing internal friction. The BEA internal design signifies a modified contact geometry that lowers operating temperatures and improves lubrication film formation. These bearings are widely integrated into heavy-duty gearboxes, mining equipment, and large-scale industrial fans. With its high-precision P5 running accuracy and integrated lubrication groove (W33), it minimizes maintenance downtime while ensuring consistent performance under extreme pressure.
