This power house servo raises the roof with an aluminum heat-sink case that offers a longer duty-cycle for those really tough applications. The performance is staggering for a servo this size. It is the first in the industry to offer a full set of titanium gears with 48 times the strength of nylon gears. Each gearset shaft uses in bronze bushings for durability and strength.
