    AI Overview
    An L-830 bearing is a specialized miniature ball bearing, most commonly identified with dimensions of 3mm x 8mm x 4mm (Inner Diameter x Outer Diameter x Width) or sometimes 3x8x3mm. 
    The most common equivalent for the 3x8x4mm L-830 is the 693ZZ (shielded) or 693-2RS (sealed) bearing. 
    L-830 Bearing Equivalents and Designations 
    • 693ZZ / L-830ZZ (3x8x4 mm): The most common replacement. "ZZ" indicates metal shields on both sides, while "L-830ZZ" is often used in the radio-controlled (RC) car and hobby industry.
    • MR83-2RS / L830-2RS (3x8x3 mm): Used in applications needing rubber seals for better protection against dust and moisture.
    • Key Dimensional Equivalent: 3mm ID x 8mm OD x 4mm Width (or 3mm width for MR83). 
    Key Features 
    • Size: Generally 3mm Inner Diameter, 8mm Outer Diameter, 3-4mm Width.
    • Material: Chrome Steel (SAE 52100) is standard for durability.
    • Seals/Shields: Available as open, shielded (ZZ), or sealed (2RS).
    • Common Applications: High-speed, light-duty applications such as robotics, dental instruments, surgical tools, radio-controlled models (RC cars/planes/helicopters), and small electric motors.
