    AI Overview
    High-speed 20mm bore bearings are typically 6204 series deep groove ball bearings (20x47x14mm), capable of handling up to 18,000+ RPM. Ideal for electric motors and machinery, these are often available with double rubber seals (2RS) or metal shields (ZZ) to ensure high-speed reliability. Common high-speed options include: 
    • 6204-2RS: 20mm Bore, 47mm OD, 14mm W, 18,000 RPM
    • 6004 Series: High speed and lighter weight options
    • Precision Angular Contact: 20mm Bore, 47mm OD (e.g., SKF) 
    Key Features of High-Speed 20mm Bearings: 
    • Design: Single row deep groove radial ball bearing for moderate radial/axial loads.
    • Sealing: Double rubber seals (2RS) or metal shields (ZZ) to exclude contaminants and retain grease.
    • Materials: Chrome steel for durability or stainless steel for corrosion resistance.
    • Applications: Ideal for high-speed electric motors, small machinery, and dental equipment.
    • Temperature: Specialized high-temp variants (e.g., C5 clearance) exist for high-speed, high-temp environments. 
    Top Manufacturers and Suppliers: 
    • SKF: Known for precision angular contact and ball bearings.
    • Nachi: Offers high-speed 6204-2rs and 6904 models.
    • McMaster-Carr: Broad selection of bearings.
    • Bearings Direct: SSUC204/SUC204 stainless steel options.
