Applications:
The 3311-BD-XL-C3 is perfectly suited for use in gearboxes, spindles, electric motors, machine tools, compressors, pumps, turbines, and other precision rotating equipment where combined bidirectional loading conditions are present. The 55mm bore size makes it suitable for medium to large-sized machinery while maintaining excellent load capacity for heavy-duty industrial operations. The slightly increased radial clearance and extended temperature range make it particularly beneficial in applications subject to significant thermal fluctuations, high-speed rotation, or where thermal expansion compensation is required.
FAG's reputation for manufacturing excellence ensures consistent quality, precision performance, and extended service life in the most challenging operating environments.
