Ultra-Thin Precision Deep Groove Ball Bearings – 6700 Series (ZZ & 2RS)

High-Grade Chrome Steel Construction
Manufactured from durable chrome steel (GCr15) for superior hardness (HRC 60+) and wear resistance, ensuring extended service life under high-speed rotation.
Precision Thin-Wall Design
Minimal cross-section (C-code) reduces weight and space requirements while maintaining radial load capacity (up to 1.8 kN for 6706ZZ), ideal for compact machinery and instruments.
Dual Sealing Options
Choose between ZZ (metal shields) for high-speed applications (e.g., drones, RC models) or 2RS (nitrile rubber seals) for dust/water resistance in industrial gearboxes or automotive components.
Mirror-Polished Raceways
Laser-engraved markings and ground surfaces (Ra ≤0.2μm) minimize friction, enabling silent operation (<20dB) for medical devices and office equipment.
Global Compliance Ready
Pre-lubricated with high-temp grease (operating range: -30°C to +120°C), compliant with ISO 9001 and ABEC-1 standards.
Bulk Discount Advantage
Direct factory pricing (50% below retail), MOQ 100pcs with customizable packaging for OEM/wholesale buyers.
Universal Fit
Interchangeable with SKF/FAG equivalents. Common replacements for treadmill motors, conveyor rollers, and agricultural machinery.
