High-Speed 6804ZZ Deep Groove Ball Bearing – Precision Engineered for Demanding Applications

Premium Chrome Steel Construction for exceptional durability and corrosion resistance, hardened to HRC 60-64 for long-lasting performance.

Ultra-Smooth 20mm ID with tight tolerance (±0.002mm) ensures vibration-free rotation at up to 15,000 RPM, ideal for CNC spindles and precision machinery.

Smart Lock Sealing (2RS/ZZ options) prevents lubricant leakage while blocking dust, perfect for food processing equipment or outdoor power tools.

Low-Friction Polyamide Cage maintains stable alignment under heavy loads (up to 1.2kN dynamic), extending service life in automotive transmissions or industrial conveyors.

Pre-Lubricated with high-temperature grease (operating range -30°C to +120°C) for maintenance-free use in electric motors and HVAC systems.

Mirror-Polished Raceways reduce wear by 40% compared to standard bearings, critical for 3D printer components and medical devices.

Direct Factory Pricing saves 30-50% over retail, with bulk discounts available for OEMs and machinery manufacturers.
