MG995R 180 Degree Servo Motor | High Torque Metal Gear Positional Servo for Robotics Projects
Disclaimer: This MG995R servo provides precise 0° to 180° angular positioning. It is not a continuous rotation servo. Do not force the output arm beyond its mechanical stops. Use an external power supply – the stall current can exceed 1.8A.
Servo Motor MG995R 180 Degree Rotation
The MG995R 180° is a high-performance, high-torque servo designed for applications requiring precise angular control. Unlike continuous rotation servos, this model allows you to command the servo to move to any specific angle between 0° and 180°. Featuring robust metal gears and a dual-bearing design, it provides the strength and reliability needed for heavy-duty robotic arms, steering mechanisms, and camera pan/tilt systems.
Specifications
- Rotation Type: Positional control (0° to 180° angular range)
- Gear Material: All-metal gears (high strength, wear resistant)
- Torque Output: 13 – 15 kg·cm (at 6V, stall torque)
- Operating Voltage: 4.8V – 7.2V (5V or 6V recommended)
- Speed (no load): ~0.17 sec/60° (at 6V)
- Current Draw (idle): ~100 – 200 mA
- Current Draw (stall/moving under load): Up to 1.8 – 2.0 A
- Control Signal: PWM (50Hz standard RC servo pulse; 0.5ms to 2.5ms typical, 1.5ms = neutral/90°)
- Bearings: Dual ball bearing (double ball bearing) for smooth, low-friction operation
- Dead band width: ~4 µs (accurate positioning)
- Dimensions: 40.7 x 19.7 x 42.9 mm (standard large servo size)
- Weight: ~55 grams
- Connector: 3-pin female JR/Futaba type (Signal, Vcc, GND)
Applications
- Robotic arms and grippers (heavy-duty joints)
- Steering mechanisms for RC cars, boats, or small vehicles
- Camera pan and tilt systems (precise angle positioning)
- Humanoid robot joints (shoulders, hips, knees)
- Industrial automation mockups and educational robot kits
- Solar panel tracking mounts (seasonal/angle adjustment)
Package Includes
- 1 x Servo Motor MG995R 180 Degree Rotation
Final note: Power supply warning – The MG995R is a high-power servo. When operating under load, it can draw significant current (up to 1A or more). Do not attempt to power this servo directly from your microcontroller’s 5V pin, as this will likely cause brownouts or damage the board. Always use a dedicated 5V–7.2V power supply (2A-3A recommended for one servo) with a common ground shared with your microcontroller. Additionally, avoid physically forcing the servo beyond its 0° or 180° endpoints — this may strip the metal gears or damage the feedback potentiometer.
