The MKS HBL575SL is a brushless chrome-titanium gear low-profile high-voltage digital servo with X6 spline output and CNC machined aluminum case. Running on 3.5–7.4V, it delivers 233.3 oz/in (16.8 kg/cm) at 7.4V with a 0.07 sec/60° transit speed in a slim 23.1mm height profile — ideal for 1/10 scale surface applications where servo bay depth is limited.
A 4-pole Japan high-quality brushless motor delivers high speed, incredible efficiency, and low power consumption. Chrome-titanium alloy gears provide precision and durability. HD 4096 resolution ensures ultra-precise positioning. The CNC machined aluminum case provides exceptional cooling and rigidity.
Note: Operating temperature is higher at 7.4V. Ensure adequate ventilation or install a cooling fan to increase airflow when running at maximum voltage.
