Application of Compact #25 Drive Sprocket for Robotics & Miniature Mechanisms
Designed for Small-Scale, High-Precision Power Transmission:
Used across robotics, hobby engineering, model vehicles, and compact automation systems, this sprocket enables smooth, efficient motion in tight spaces. Common applications include robotic actuators, mini conveyors, laboratory instruments, compact sorting units, and educational mechanical projects.
Optimized for Tight Spaces, Speed & Precision:
Its small bore, low tooth count, and compact geometry make it ideal for builds where space is limited and high rotational speed with moderate torque is required. Threaded mounting holes support secure installation in custom automation platforms and precision-driven assemblies.
Trusted by Robotics & Hobby Engineering Brands:
Frequently used by robotics kit manufacturers, custom automation integrators, laboratory equipment builders, and hobby-grade model makers. Compatible with systems from Flipsky, Makeblock, and any lightweight mechanism using #25 roller chain.
Summary
A compact, precision-focused sprocket engineered for robotics, model engineering, and miniature automation systems. It delivers smooth chain engagement, secure fitment, and reliable performance in small-format mechanical applications.
