High-Speed Deep Groove Ball Bearing 61904-2Z – Precision & Durability for Demanding Applications
Ultra-thin 9mm wall design maximizes space efficiency without compromising load capacity, ideal for compact machinery and precision instruments. Premium chrome steel construction with advanced heat treatment ensures extended lifespan under high-speed rotation (up to 15,000 RPM) and heavy radial loads. Double-sealed (2Z) design with nitrile rubber seals prevents dust/contaminant ingress while retaining grease, reducing maintenance frequency in harsh environments. Precision-ground raceways and balls minimize friction (ABEC-1 standard), delivering whisper-quiet operation for medical devices, drones, and HVAC systems. Versatile for industrial automation, electric motors, and automotive components – compatible with both vertical and horizontal mounting configurations. Bulk order discounts available – global wholesale pricing with guaranteed 48-hour dispatch from our bonded warehouses.
