Industrial use made of ABS plastic, with five 6 mm ball bearing can easily bear the weight of 4.9Kg, very durable.
The base supports the HS-311, HS-422, HS-475, HS-485 and HS-645 and other servo. All in all it was a very good arm rotating base.
Servos can plug in directly arduino arduino IO expansion board servo drive servo library easily.
Actuator Operating voltage: 4.8-6V, top diameter: 9.5MM, bottom diameter: 10MM, height: 5MM.
