S61701-2RS Stainless Steel Thin Section Deep Groove Ball Bearing 12x18x4mm Double Rubber Sealed Mini Bearing

S61701-2RS is single row ultra-thin miniature stainless steel deep groove ball bearing, standard metric dimension 12mm inner bore × 18mm outer diameter × 4mm width.

Full Model Code Explanation:

• S: Full stainless steel material, excellent anti-rust & anti-corrosion performance
• 6: Deep groove ball bearing type, bear bidirectional radial and light axial load
• 17: Extra thin light series, ultra-small radial cross-section
• 01: Nominal inner bore size 12mm
• 2RS: Double sides contact rubber lip seal, fully closed inner cavity with pre-filled lubricant

Adopts AISI440C stainless steel inner ring, outer ring and steel balls, matched with thin stamped stainless steel cage. Ultra-thin lightweight structure saves limited installation space of mini precision equipment. Double-side 2RS contact rubber seal effectively block moisture, dust, fine powder and weak chemical vapor from entering raceway, avoid frequent re-lubrication. Low friction design supports stable high-speed low-noise rotation. Widely used in medical testing instruments, miniature motor, precision optical equipment, small household appliances, dental equipment, food processing small machinery, electronic automation miniature rotating shafts and all compact anti-corrosion precision transmission devices.

Mounting dimension drawings, miniature motor assembly matching guides and humid environment anti-rust durability test reports can be provided on customer request.

1. Full AISI440C stainless steel construction, resistant to water vapor, weak acid, salt mist and workshop dust, suitable for medical, food and humid working environment.
2. 617 ultra-thin thin-wall series design, minimal radial thickness, realize miniaturization and lightweight layout of small precision equipment.
3. Double-sided 2RS reinforced contact rubber seal, good sealing performance to lock internal grease and isolate external contaminants, long-term maintenance-free operation.
4. Super-finished smooth deep groove raceway and stainless steel ball surface, ultra-low friction torque, stable low-vibration low-noise high-speed rotation performance.
5. Thin stamped stainless steel cage, small centrifugal loss during high-speed rotation, no deformation or abnormal noise under continuous long-time operation.
6. Standard unified interchangeable metric dimensions, fully compatible with global mainstream S61701-2RS miniature stainless steel bearings, direct replacement without modifying miniature shaft and housing structure.
