💡 ¿Para qué sirve una rueda dentada en un sistema de transmisión?

Chain sprockets drive machinery by transferring rotary motion from a drive chain to a shaft, forming the heart of power transmission.

- Follows ISO 04C chain size and tooth count for proper meshing
- Steel with black oxide coating resists wear in tough environments
- Commonly used in milling machines, drilling rigs, conveyors
