Extreme Torque Density: 85kg.cm in a Standard Chassis
The XQ-POWER RS8185D represents the absolute limit of torque performance in a 20mm chassis. Specifically, it is engineered for heavy-duty industrial applications that demand massive holding power and high-voltage efficiency. By supporting up to 16.8V (4S LiPo) direct drive, this actuator delivers an incredible 85kg.cm (1180 oz-in) torque, ensuring total control under the most extreme mechanical loads.
Industrial-Grade RS485 Communication
Significantly, the RS8185D features the robust RS485 differential signaling protocol. This interface provides superior noise immunity against electromagnetic interference (EMI) from high-power factory machinery. Moreover, the RS485 bus supports multi-node networking, allowing you to synchronize an entire array of these 85kg actuators via a single serial port over long distances.
Advanced Metallurgy & 4S Voltage Efficiency
Undoubtedly, managing 85kg of torque requires elite structural integrity. The RS8185D features a precision-machined full CNC aluminum case (44mm height) to maximize thermal dissipation. The internal stainless steel gear set and dual ball bearing system ensure perfectly concentric rotation. Consequently, this rugged design guarantees reliable performance in mission-critical automation tasks.
