Spline Adapter 29mm x 26 tooth

The Spline Adapter 29mm x 26 tooth by UNICLUTCH is a precision coupling component engineered for high-torque power transmission in tactical weapon systems, automotive applications, and rugged field equipment. Built for operators and maintainers who demand reliability under extreme conditions, this adapter bridges drive shafts and mechanical assemblies where standard connections fall short. Whether you're managing armorer-level maintenance on crew-served weapons, restoring legacy military platforms, or servicing heavy-duty tactical vehicles, this spline adapter delivers the mechanical integrity required for mission-critical performance.

The 29mm bore with 26-tooth spline profile ensures maximum surface engagement and load distribution across mating components, minimizing backlash and wear during repeated cycling or sustained rotational stress. Precision-machined geometry allows smooth, interference-free insertion while maintaining zero play under operational load—critical for indexing accuracy in firearms action systems or drivetrain assemblies. The adapter's robust construction is engineered to withstand shock loads and temperature extremes typical of field deployment, making it equally suitable for military small arms maintenance, crew-served weapon systems, or industrial tactical equipment requiring bulletproof mechanical coupling.

This component is essential for armorers, maintenance technicians, and equipment specialists restoring or servicing weapons platforms where original OEM spline couplings have worn or require replacement. Installation requires proper alignment fixtures and calibrated tools to ensure the 26-tooth profile seats flush with mating spline bores. Compatible with any system featuring a 29mm spline bore—verify your specific platform's drive shaft specifications before ordering. The 1.055 lb compact footprint fits tight equipment bays while delivering the torque capacity operators expect from UNICLUTCH precision engineering.
