Product overview
The KST X20-2208 V8.0 is a standard servo for angular actuation. Its construction combines an aluminum alloy case, a brushless DC motor and hardened steel gearing, with a potentiometer for position sensing and six ball bearings. The case measures 40 × 20 × 40 mm ±0.2 mm, establishing the component envelope for installation planning. Weight is 72 g ±10%, so both the dimensional tolerance and weight tolerance are relevant when allocating mounting space and component mass.
Electrical integration requires DC6.0–8.4V, with a rated voltage of DC7.4V and a working-frequency specification of 1520us/333Hz. Torque is 18 Kgf. C m at 6.0V, 22 Kgf. C m at 7.4V and 25 Kgf. C m at 8.4V. Corresponding speeds are 0.09, 0.08 and 0.07 seconds per 60°, respectively. These ratings depend on supply voltage. Default travel is ±50°, or 100° total, and the temperature range is −20 °C to +65 °C.
