The 108 RICH is an ultra-compact double-row self-aligning ball bearing designed for small-scale applications where shaft alignment is difficult to maintain. Featuring an 8 mm bore, this bearing belongs to the 100 series and is equipped with a common spherical raceway in the outer ring. This allows the inner ring and the two rows of balls to pivot freely, effectively compensating for angular misalignments caused by mounting inaccuracies or shaft deflection. The robust steel cage ensures precise ball guidance and structural stability even under high-speed operation. Weighing only 0.013 kg, this bearing is an ideal solution for precision instruments, small laboratory equipment, and micro-mechanical assemblies where low friction and the ability to self-correct alignment are critical for operational longevity. Its open design allows for seamless integration into oil-mist or grease-lubricated systems.
