The ServoCity 3/8" Round Servo Shaft (25 Tooth Spline, 36mm Length) transforms a servo's H25T spline into a 3/8" round shaft, facilitating diverse motion applications. This shaft is designed to be supported by a 3/8" ID bearing, effectively isolating radial loads from the servo. Its round profile allows for flexible hub positioning, enabling the driving of gears, sprockets, or pulleys to mobilize projects. Note: This product does not include a servo screw; use the one provided with your servo to attach this shaft.
