Custom Finger Gear for Robot Hands | Module 0.5 Precision Finger Gear Shaft
Custom Finger Gear for Robot Hands
Precision shaft-integrated finger gear designed for robotic hands, compact actuator modules and miniature motion transmission systems. This custom finger gear combines fine tooth geometry, stable shaft alignment and compact structural design for demanding robotic applications.
Product Overview
This Custom Finger Gear is developed for robot finger transmission systems where compact size, repeatable meshing accuracy and stable torque transfer are critical. The part adopts a shaft-type gear structure, making it suitable for robotic hand joints, finger actuation assemblies, precision reducers and miniature electromechanical motion systems.
Compared with general miniature gears, a robotic finger gear must balance tooth precision, shaft concentricity, mounting reliability and fatigue resistance in a very limited installation space. This design is therefore well suited for applications that require accurate positioning, compact packaging and long-cycle operation.
Core Advantages
- Compact shaft gear structure for tight robotic finger assemblies
- Precision tooth data suitable for stable meshing and consistent motion output
- Integrated form helps reduce assembly stack-up compared with split parts
- Suitable for custom robotic fingers, miniature actuators and motion control units
- Supports OEM development based on drawing, sample or application requirements

Why It Fits Robot Fingers
Robotic finger transmissions require compact gears that can deliver precise motion in a small envelope. This custom finger gear is suitable for mechanisms where backlash control, stable meshing and compact shaft integration matter.

Custom Finger Gear Manufacturing Notes
For robot finger gear projects, product quality is not decided by tooth count alone. Shaft concentricity, shoulder transition, surface treatment, heat treatment consistency and inspection method all influence actual transmission behavior. In compact robotic hands, even small deviations can affect synchronization, backlash and long-term repeatability.
This is why custom finger gears are usually developed as application-specific parts rather than general catalog items. If your project has defined torque, life cycle, mounting structure or size constraints, the gear can be further optimized in geometry and process route to better match the intended robotic mechanism.
