The self-aligning ball bearing adopts a spherical outer ring design, which can automatically compensate; 1.5° ~± 3° Axis deviation effectively reduces installation errors and vibration effects, suitable for medium and low load, high-speed working conditions, and has wear-resistant and impact resistant characteristics. It is a stable choice for equipment such as transmission shafts and fans.
