High-Precision Motion Control
Achieve exact linear positioning and accurate velocity control in your automated mechanical systems with this 20-tooth GT2 timing pulley. Designed specifically for low-backlash power transmission, this drive component is critical for desktop 3D printers, high-resolution CNC engravers, precision laser cutters, and custom robotics platforms.
Optimized GT2 Tooth Profile
The specialized GT2 curvilinear tooth profile features rounded teeth that mesh perfectly into matching timing belts, distributing operational load evenly across the belt interface. This reduces tooth stress, minimizes hysteresis, and eliminates the rotational slop commonly encountered with older trapezoidal profiles such as MXL or XL. This pulley is precision-machined exclusively for use with 6mm wide GT2 timing belts.
Durable Machined Aluminum Construction
Crafted from lightweight, high-grade aircraft aluminum alloy, this timing pulley offers exceptionally low rotational inertia combined with maximum wear resistance. The dual integrated M3 set screw threaded holes enable a tight, secure attachment to any 5mm diameter shaft, ensuring reliable torque transfer without slipping during rapid directional changes or high-acceleration moves.
Broad System Compatibility and Applications
Featuring an accurate 5mm internal bore diameter, this pulley mounts seamlessly onto standard NEMA 17 stepper motor shafts, BLDC motors, and precision steel axle shafts. It serves as an ideal replacement part or performance upgrade for popular open-source 3D printers, automated pick-and-place devices, and specialized industrial actuators.
