DIN6 Micro Spline Gear Shaft | Integrated Fine Pitch Spline Shaft for Industrial Applications

Precision Micro Spline Gear Shafts: Integrated Zero-Backlash Transmission for Compact Systems

When space is limited and precision is non-negotiable, our micro spline gear shafts deliver the rigid, reliable performance you need for high-tech compact systems. Unlike traditional assembled gear-and-shaft designs, these integrated components feature precision-machined splines directly on the shaft body, eliminating assembly backlash and ensuring consistent torque transfer, even under high-cycle operation.
