CNC Aluminum 25T Round Servo Horn Disc (20 mm) | Servo Horn / Arm | RC & Robotics Actuator Linkages
Description
Enhance your actuation setups with the SPIDER Automation CNC Aluminum 25T Round Servo Horn Disc. Designed as a versatile upgrade for high-torque actuators like the MG995 and MG996 servo motors, this round metallic disc replaces weak stock plastic horns to eliminate flexing and stripping. Featuring a precise 25-tooth spline interface and a compact 20 mm circular profile, it offers multiple mounting holes for complex linkage connections, custom pulleys, and robotic attachments, ensuring absolute mechanical reliability.
Key Features
- Standard 25-Tooth Spline: Precision-broached 25T interface designed to lock firmly onto standard output shafts without rotational backlash.
- Solid Aluminum Build: Premium metal construction offering superior tensile strength compared to conventional plastic horns.
- Symmetrical 20 mm Circular Disc: Compact round footprint allowing balanced multi-directional connection points.
- M3 Threaded Mounting Points: Outfitted with robust M3 screw provisions for secure component attachment.
- Ultra-Lightweight Profile: Weighing just 2 grams, it adds maximum structural strength without burdening servo load limits.
Benefits
- Eliminates Spline Stripping: Prevents teeth wear during high-torque stalls or sudden impacts.
- Symmetrical Load Distribution: Round disc geometry distributes mechanical stress evenly across the servo shaft.
- Zero-Flex Performance: Solid aluminum structure ensures 100% direct force transfer to mechanical assemblies.
- Enhanced Lifespan: Outlasts factory plastic horns, minimizing maintenance in demanding prototypes.
- Universal Compatibility: Drop-in fit for standard MG995, MG996, and other 25T servo motors.
- Includes Hardware Set: Bundled with an appropriate set of M3 screws for immediate installation.
Applications
- Robotic Winch & Cables: Winding spools and cable-pulling linkages in custom mechatronics.
- Steering & Drive Turrets: Symmetrical rotation hubs for pan-tilt camera platforms and radar scanners.
- RC Cars & Boats: Custom steering and auxiliary throttle actuation rigs.
- Industrial Automation: Custom mechanical testing fixtures requiring repetitive circular positioning.
- Mechanical Pulleys: Acting as a direct-drive pulley or mounting plate for lightweight cords.
- Robotics Education: Building advanced mechanical joints in student projects.
