Applications:
The 3306-ATN9/C3 is perfectly suited for use in gearboxes, spindles, electric motors, machine tools, compressors, pumps, and other precision rotating equipment where combined bidirectional loading conditions are present. The compact 30mm bore size makes it particularly suitable for smaller to medium-sized machinery while maintaining excellent load capacity for demanding industrial operations. The slightly increased radial clearance is especially beneficial in applications subject to temperature fluctuations or where thermal expansion compensation is required.
SKF's reputation for manufacturing excellence ensures consistent quality, precision performance, and extended service life in the most challenging operating environments.
