This precision-engineered deep groove ball bearing features an innovative thin-walled design that maximizes space efficiency while reducing overall weight. The 6704 series bearing, measuring 20x27x4mm, delivers smooth and quiet operation in both radial and axial directions thanks to its optimized deep groove raceway construction. Available with ZZ metal shields or RS rubber seals, this bearing offers flexible protection options against contamination to match your specific application needs. Crafted from premium bearing steel, it ensures reliable performance and extended service life under demanding conditions. Part of a comprehensive size range spanning from 6700 to 6710 series, this versatile bearing is ideal for applications where space constraints and weight considerations are critical while maintaining robust load-bearing capabilities. The thin-wall construction makes it particularly suitable for compact machinery designs and high-speed applications requiring precise rotation and minimal friction.
