Detailed Specifications










The HS-485HB servo is one of the best deals going. Nearly 84 oz-in. of power for under $17. We use this servo for all types of robotic applications. HS-485HB updates the very popular HS-475HB by adding more torque and greater speed. With a top ball bearing, heavy duty, high impact Karbonite™ gears and high performance circuitry, the
HS-485HB offers lots of torque and features excellent centering and resolution.
Note: The HS-485HB servo spline is slightly oversized and will be a very snug fit into broached servo accessories. After installed the first time, later assembly will be easier.


 83.3 oz-in.


 0.18 sec/60°

This servo can operate 180° when given a pulse signal ranging from 600usec to 2400usec. Since most R/C controllers cannot generate this wide of signal range, you will need to purchase our servo stretcher for 180° operation.
