Precision SMR85ZZ Miniature Deep Groove Ball Bearing
Ultra-smooth stainless steel construction (Grade 420) resists corrosion for harsh environments. Hardened chrome steel balls (Grade 25) ensure <15μm radial runout for vibration-free operation.
Mirror-polished raceways reduce friction by 30% vs standard bearings. Dual rubber ZZ shields block dust while allowing high-speed rotation (18,000 RPM).
Perfect for dental tools, drone motors, RC cars, and miniature gearboxes. Vacuum-sealed packaging prevents oxidation during storage.
Exact dimensions (5x8x2.5mm) match industrial blueprints. Laser-etched part numbers for traceability. Bulk discounts available for OEM/wholesale buyers.
