This series consists of medium-width, flanged deep-groove ball bearings, representing the most versatile miniature specifications for industrial applications. The 60 series strikes an excellent balance between dimensions, rotational speed, and load capacity. The flange thickness and outer ring width are optimized to ensure uniform circumferential support for the outer ring during high-speed rotation, thereby minimizing operational vibration and noise.
Bearing Features
Fabricated from SUS420 stainless steel, these bearings offer favorable magnetic permeability, providing a distinct advantage over 300-series stainless steels in sensor-integrated applications requiring magnetic sensing control. With high standardization—featuring flange diameters and thicknesses that comply with international standards—they facilitate rapid replacement in precision fans, encoders, and miniature motors, significantly reducing equipment downtime for maintenance.
