FLW686ZZ Integral Flanged Miniature Deep Groove Ball Bearing Double ZZ Metal Dust Shield 6x13x5mm Precision Automation Equipment

The FLW686ZZ is a thin-wall miniature deep groove ball bearing with one-piece positioning flange and double-sided ZZ metal dust shields, interchangeable with F686ZZ standard flanged bearing, core dimension 6×13×5mm, total flange width 5mm. It supports radial load and minor bidirectional axial load; integrated outer flange replaces circlips for axial limit, double steel shields block fine dust and particles, pre-filled long-life grease, widely used in miniature automation sliding shafts, precision testing instruments, model motors and small 3C rotating components.
