Precision Torque Splines

Explore Helix Linear Technologies’ Precision Torque Spline CAD Library, a complete collection of downloadable 3D models and technical drawings engineered to support advanced mechanical design, motion system integration, and efficient product development. Our CAD resources provide accurate geometry, dimensional data, and assembly details so engineers can confidently evaluate torque spline solutions within their assemblies and automation systems.



Precision torque splines are high-performance mechanical interfaces used to transmit torque between rotating components with minimal backlash and maximum accuracy. Commonly applied in robotics, servo systems, aerospace actuation, and precision gearboxes, these splines enable smooth power transfer and precise motion control. With our ready-to-use CAD models, design teams can visualize spline engagement, perform interference checks, and validate key fits early in the design cycle.



Each precision torque spline CAD model in the library is compatible with major CAD platforms and includes complete geometric information that supports interference checking, mating fits, and manufacturing documentation. By incorporating these digital assets directly into your CAD assemblies, you reduce engineering time, minimize modeling errors, and ensure a more predictable integration process.



Helix Linear Technologies’ precision torque spline CAD resources empower engineers to optimize system performance, ensure mechanical integrity, and accelerate time-to-market for complex motion designs. Download the models you need today to advance your next precision power transmission application with confidence.
