RC Servo GT2 Pulley
The RC Servo 25T Spline to GT2 Pulley is a precision-engineered aluminum component designed to bridge the gap between hobbyist RC servos and industrial-style belt drive systems. Most standard high-torque servos (such as those from Futaba, Savox, or MG996R series) use a 25-tooth (25T) output spline. This pulley mounts directly onto that spline, allowing you to use 6mm wide GT2 timing belts for precise motion control.
Key Technical Specifications:
Compatibility: Fits standard RC servos with a 25T Spline (Common in TowerPro, Futaba, Savox, and high-end coreless servos).
Tooth Profile: GT2 (2GT) – specifically designed for linear motion and precision with minimal backlash.
Pitch: 2mm.
Belt Width: Optimized for 6mm wide timing belts.
Tooth Count Options: Available in 20-tooth (RC2GT-20T-6) or 36-tooth (RC2GT-36T-6) configurations to allow for different gear ratios and torque outputs.
Material: Lightweight, high-strength 6061 Aluminum, offering better durability and heat dissipation than plastic servo horns.
Applications:
Medical & Lab Automation: Using coreless servos for small-scale precision pumping or sample positioning.
Robotics: Creating compact linear actuators for robotic arms or grippers where space is limited.
DIY Projects: Camera sliders, pan-tilt heads, and small-scale CNC or 3D printer experimental builds.
Education: Demonstrating the conversion of rotational motion to linear motion using timing belts.
Why Use This?
Standard plastic servo horns often flex or strip under high loads. This aluminum pulley provides a rigid, "no-slip" connection. By using a belt-drive system, you can move loads over longer distances than a standard linkage allows, while maintaining the high holding torque of a coreless servo.

RC Servo is Not included.
RC Servo especially coreless motor servos can be widely used in small devices of medical or analysis. As the positive actuator using pulley and belt driven construction where to get a pulley which can be used onto popular 25T spline is the key question.
