The XRAY 305916 Narrow Pinion Gear suits hobbyists who need accurate, low-mass gearing for T4 2017 machines. Built from aircraft-grade duraluminum, this unit is 1.5mm thinner and about 25% lighter than typical pinions, offering a slim option for refined drivetrain dynamics.
Produced on XRAY precision gear machinery, the narrow pinion delivers high concentricity thanks to tight tolerances. Each gear receives chamfering and a run-in process before a specialised hard-coat is applied to extend service life under load.
Made to match spur gears with 16T/48 dimensions, the XRAY 305916 works particularly well with XRAY spur gears to reduce throttle on/off clatter. The narrower profile helps smoother tooth engagement for a quieter overall drivetrain.
