6900ZZ Single Row Thin Wall Miniature Deep Groove Ball Bearing Double ZZ Metal Dust Shield 10x22x6mm Micro Automation Equipment

The 6900ZZ thin-wall miniature deep groove ball bearing adopts double-sided ZZ non-contact metal dust shields, standard dimension 10×22×6mm. It bears radial load and slight bidirectional axial load, features ultra-light thin-wall structure and low rotational friction. Double steel shields block fine dust and particle impurities, lock internal long-life lubricating grease, widely used in micro motors, small cooling fans, automation miniature shafts, optical instruments and 3C electronic rotating assemblies.

• Ultra-thin wall 69 series design saves radial installation space for compact miniature equipment
• Non-contact ZZ metal shields bring minimal friction loss, great dust resistance without limiting high speed
• Precision superfinished raceway and tiny steel balls deliver quiet, stable low-vibration rotation
• High-hardness quenched bearing steel provides outstanding wear resistance for long continuous operation
• Multiple optional variants: open 6900, splash-proof 6900-2RS, stainless steel anti-rust version
• ABEC-1 / ABEC-3 precision grades available for optical and lab precision testing devices
