37mm 25T Metal Extension Steering Servo Arm

Let's Break down the key Features and Meanings of its Specifications:

Length: The "37mm" dimension refers to the length of the servo arm. This is the distance from the center of the servo's output shaft to the outer edge of the arm.

Spline Count: The "25T" specification indicates the number of teeth on the spline of the servo arm. In this case, it has 25 teeth. The T stands for "tooth," and the 25T is a common standard for many servos in the RC hobby.

Material: The use of the term "Metal" indicates that the servo arm is made of metal, which is often aluminum or another alloy. Metal servo arms are chosen for their durability and strength.

Extension: The term "Extension" in the name suggests that this servo arm provides an extended reach compared to standard servo arms. The longer length can be beneficial in specific RC applications where a greater range of motion or leverage is required.
