Small servo motors are the workhorse of micro RC and hobby robotics. This range covers 9g and 14g units in nylon and metal gear versions, running 4.8 to 6V with torque and speed listed for each model.
SG90 and MG90S Class Micro Servos
The SG90 is the nylon gear standard for light loads, while the MG90S adds metal gears in the same footprint for linkages that see shock loads.
Torque and Speed at 4.8 to 6V
Micro servos are rated at 4.8V and 6V, and torque rises with voltage. Match the rating to what your receiver or BEC actually supplies.
Nylon vs Metal Gear Micro Servos
Nylon gears are lighter and quieter; metal gears survive crashes and stall loads. For robot arms and steering linkages, metal is usually the cheaper choice over time.
Using Hobby Servo Motors with Arduino and Flight Controllers
Micro servos run from a standard PWM signal, so they work with Arduino boards, flight controllers and RC receivers without extra hardware.
Bulk Supply
Bulk packs and OEM labels are available for builders, schools and distributors.
Frequently asked questions
What is the difference between SG90 and MG90S?
The SG90 uses nylon gears and the MG90S uses metal gears; the MG90S also has slightly higher torque.
How much torque does a 9g servo have?
Typically around 1.8kg-cm at 4.8V and about 2.2kg-cm at 6V.
What is the best micro servo for a robot arm?
A metal gear micro servo in the 9g to 14g class is the usual choice for small arms and grippers.
Do you sell micro servos in bulk?
Yes, with OEM labels and packaging available.
