A 21-Teeth Non-Segmented Sprocket is a solid wheel with 21 evenly spaced teeth designed for the undercarriage frame of a mini hydraulic excavator. It plays a crucial role in driving the track and enabling the excavator's movement. The non-segmented design ensures durability and efficient power transmission. Each tooth on the sprocket engages with the track chain link, propelling the excavator forward or backward.Attributes:• Enhanced durability due to solid, non-segmented design• Efficient power transmission for better traction and improved performance • Improved reliability to withstand heavy loads and hard conditions• Enhanced performance with smooth operation and increased maneuverability Applications:This 21-Teeth Non-Segmented Sprocket is mounted on the undercarriage and engages with the track chain to provide motion and traction.
