Description
- ServoBlock®(standard Size, 25 Tooth Spline, 8mm OD Shaft)
- Isolates radial loads from servos
- Facilitates easy positional adjustments
- Allows infinite indexability of components
- Enhances support with robust block structure
- Offers versatile attachment with side mounts
The ServoBlock®(standard Size, 25 Tooth Spline, 8mm OD Shaft) is engineered to isolate radial loads from standard size servos, featuring an H25T output spline. It incorporates an 8mm diameter round shaft, which facilitates the installation of an 8mm clamping hub, enabling swift and straightforward positional adjustments of attached components without disassembly.
The round shaft's design allows for infinite indexability of motion components such as hubs and couplers, while its length provides enhanced axial adjustment for attached components. The robust block structure enhances support for the servo shaft by optimizing the distance between the servo-to-shaft fastening point and the bearing that supports the shaft. Additionally, the ServoBlock offers versatile attachment options through its side mounts, which are compatible with goBILDA 16mm square patterns.
