DOLUNTO Brass Shaft Coupler – High Quality Motor Shaft Connector for DIY Robotics

DOLUNTO Brass Shaft Coupler – High Quality Motor Shaft Connector for DIY Robotics

DOLUNTO Brass Shaft Coupler is a professional-standard mechanical connector engineered to provide accurate, stable, and vibration-free coupling between motor shafts and mechanical components. Constructed from 100% solid brass, the coupler offers exceptional rigidity and durability, making it suitable for continuous, high-load, and high-speed applications.

This coupler is precision-machined with tight tolerances to ensure perfect concentricity and alignment between shafts. Proper alignment reduces wobble, prevents slippage, improves torque transmission efficiency, and extends both motor and gearbox lifespan. The internal bore is manufactured with a highly accurate diameter, ensuring a snug fit that enhances mechanical stability.
High-strength set screws, also known as grub screws, are used in the coupler to create a strong and non-slip connection by applying consistent pressure to the motor shaft. Even in the face of abrupt direction changes or high torque loads, this design guarantees that the coupler stays securely in place.
