HSR-5990TG Servo

The bottom offers a pivot point that is inline with the output drive on the opposite side.

Ultra strong Titanium gears offer unbeatable strength and tight mesh over thousands of cycles.

The HSR-5990TG upper case incorporates brass bushings for the servo gear shafts for longevity and smooth operation.

Programmability features and state of the art hardware make the HSR-5990TG servo one of the most advanced in any industry.

The replacement for the amazing HSR-5995TG is finally here and is the new HSR-5990TG. This servo raises the bar even higher when it comes to servo technology. Now with an aluminum heat-sink case that offers a longer duty-cycle for those really tough applications. The performance is still staggering for a servo this size especially when installed in our ServoPower Gearbox (over 2,000 oz-in. or torque). Right out of the box, this servo operates a full 120° (140° full trims). A full set of titanium gears (a first in the servo industry) offers 48 times the strength of nylon gears. Each gearset shaft rides in bronze bushings for durability and strength. We offer the HSR-5990TG servo in two configurations, continuous rotation (potentiometer is left outside the servo case) and reverse rotation. We know that this is not a cheap servo but you definitely get what you pay for - you will be impressed!
