    AI Overview
    High-speed 624 bearings (4x13x5mm) are miniature deep groove ball bearings designed for high-RPM applications like 3D printers, small motors, and robotics. Common variants include 624ZZ (metal shielded) and 624-2RS (rubber sealed). They often feature chrome steel for durability, with speed capabilities exceeding 20,000 RPM up to 67,000+ RPM in high-quality versions. 
    Key Features and Specifications 
    • Dimensions: 4mm (ID) x 13mm (OD) x 5mm (Width).
    • High Speed Capability: Standard, high-quality steel bearings (e.g., SKF) can reach 67,000 r/min limiting speed, or 110,000 r/min reference speed.
    • Shielding/Sealing: ZZ (metal shields) or 2RS (rubber seals) to prevent contamination and retain lubricant.
    • Material: Typically high-grade chrome steel or stainless steel for corrosion resistance.
    • Materials Options: Hybrid ceramic bearings offer superior speed, lower friction, and better cooling compared to standard steel.
    • Applications: Motors, precision equipment, robotics, 3D printers, RC helicopters, and handpieces. 
    Performance Highlights 
    • Low Friction & Low Noise: Engineered for smooth operation at high speeds.
    • Heat Dissipation: Metal shields (ZZ) help dissipate heat under high stress.
    • Options: Available in C3 (larger clearance) for higher temperatures and even greater speeds. 
    Common Part Numbers 
    • 624-ZZ (Metal shield, double side)
    • 624-2RS (Rubber seal, double side)
    • 624 (Open)
    • V624ZZ (V-groove version) 
    These bearings are essential for components requiring low friction and long service life, such as high-speed motor components and precision instruments.

    What is considered high speed for a bearing?
    The rotational speed or RPM (revolutions per minute) that is considered “high-speed” for a bearing can vary depending on the specific application, bearing type, size, and design. However, generally speaking, high-speed bearings are designed to operate reliably at rotational speeds greater than 10,000 RPM.Feb 15, 2024

    What bearings are suitable for high speed?
    Super precision ball bearings are a versatile choice for high-speed applications. They are reliable and can handle both axial and radial loads. Their design eliminates the need to use them in pairs, making them particularly suitable for environments with limited space, where compact and efficient solutions are needed.Jan 28, 2025
