THIN SECTION METRIC FIT: Model: 6902-ZZ (Also compatible with 61902-ZZ, 6902Z). Exact Dimensions: 15mm Inner Diameter (Bore) x 28mm Outer Diameter (OD) x 7mm Width. Engineered with a space-saving, thin-wall profile perfect for compact mechanical assemblies
DOUBLE METAL SHIELDED FOR MAX RPM: Unlike rubber-sealed bearings, this 6902 version features rigid dual metal shields (ZZ). This design effectively blocks dust and debris while maintaining exceptionally low friction, unlocking maximum rotational speed for your high-performance motors
LIGHTWEIGHT & HIGH SPEED: Forged from premium Chrome Steel (ABEC-3) and factory pre-lubricated with high-temperature machine grease. It delivers lightning-fast, buttery-smooth rotation with minimal heat buildup, ideal for weight-sensitive drones and robotics
STRONG STRUCTURAL INTEGRITY: Despite its thin cross-section, the solid chrome steel construction ensures excellent radial load distribution and wear resistance. It outlasts cheaper carbon steel alternatives, providing a reliable, long-lasting lifespan
VERSATILE DRY-ENVIRONMENT USE: The ultimate precision replacement bearing for high-speed, indoor, or shielded mechanics. Highly recommended for electric motors, e-scooter internal drives, 3D printers, HVAC fans, and power tools. Note: For wet/outdoor use like bicycle hubs, please choose our 6902-2RS rubber-sealed version
