16008 40x68x9mm Thin Section Open Single Row Deep Groove Ball Bearing

1. Product Overview

16008 belongs to 16000 series thin-section single row open deep groove ball bearing, standard metric dimension 40×68×9mm, ultra-narrow thin cross-section design to save axial installation space and reduce equipment overall weight. Open type structure allows continuous circulating oil & grease lubrication; super-finished deep raceway can bear radial load and bidirectional light axial load simultaneously, featuring low noise, low friction and stable high-speed rotation performance. Equipped with high-precision steel balls and stamped steel cage, stable operation under long-term light & medium load. Widely used in textile high-speed spindles, printing machine paper feed rollers, precision automation equipment, small industrial high-speed motors, optical testing instruments and lightweight conveyor machinery.
