Cerámica de 2x5x2,5 Shielded Juego de rodamientos de bolas en miniatura con doble rodamiento ZZ Shields Grasa prelubricada. Fabricada en acero aleado 52100 para una alta durabilidad y baja fricción. Ajuste preciso para modelos de micromaquinaria con control remoto y proyectos de robótica.

These tiny bearings measure 2x5x2.5 mm and function as a sealed ball bearing using ceramic Si3N4 balls with ZZ shields to resist dust. Pre-lubricated with grease, they’re ideal for precise, low-friction motion in micro motors, 3D printers, compact gear systems, and other small linear motion assemblies.

✅ 2 mm bore, 5 mm outer diameter, 2.5 mm width
✅ Ceramic Si3N4 balls with ZZ shield seals for dust protection
✅ Pre-lubricated with grease for immediate use
✅ 52100 chrome steel races for durability
✅ One bearing per package (single unit)
