F626ZZ Integral Flanged Mini Deep Groove Ball Bearing Double ZZ Metal Dust Shield 6x19x6mm Automation Positioning Roller Equipment

The F626ZZ is a miniature deep groove ball bearing with integrated outer positioning flange and double-sided ZZ non-contact metal dust shields, standard dimension 6×19×6mm. The one-piece outer flange serves as axial stop to avoid extra circlips; double metal shields block fine dust and debris, retain internal long-life lubricating grease. It bears radial load and slight bidirectional axial load, runs stably at high speed, widely used in automation guide rollers, miniature positioning shafts, model motors, optical testing instruments and 3C transmission components.

• Integrated outer flange realizes one-step axial positioning, reduces assembly parts and mounting time
• Non-contact ZZ metal shields generate low friction, good dust resistance without restricting high rotation speed
• Medium-size steel balls deliver higher load capacity than thin-wall 68/69 series flange bearings
• Superfinished raceway and steel balls ensure low vibration, quiet and smooth continuous operation
• High-hardness quenched bearing steel improves wear resistance under frequent reciprocating movement
• Multiple optional variants: open F626, splash-proof F626-2RS, stainless steel anti-rust version
• ABEC-1 / ABEC-3 precision grades available for optical and laboratory precision equipment
