GT2 80 Teeth Timing Pulley 5mm Bore for 6mm Belt

The GT2 80 Teeth Timing Pulley with a 5mm bore is a high-precision aluminum synchronous pulley designed for 6mm wide GT2 timing belts. It features a precise 2mm pitch and 80 teeth, offering excellent torque transfer, minimal backlash, and highly accurate positioning. This makes it an essential component for reducing gear ratios, increasing resolution, or building custom reduction drives in stepper motor systems.

Engineered specifically for high-performance 3D printers (such as Voron, RepRap, and custom coreXY builds), DIY CNC machines, laser engravers, and robotic actuators. It is fully compatible with standard NEMA 17 stepper motors featuring a 5mm shaft. The dual M4 set screws ensure a secure, slip-free lock on the motor shaft, maintaining perfect synchronization even during high-speed directional changes.

Features:

• High-Quality Aluminum Construction: CNC-machined from premium aluminum alloy for high durability, low weight, and excellent wear resistance.
• 80-Tooth High-Torque Design: Provides a larger contact area with the GT2 belt, preventing belt slippage and ensuring smooth motion.
• Precise 5mm Bore: Fits perfectly onto standard 5mm stepper motor shafts (like NEMA 17) without wobble or runout.
• Optimized for 6mm Belts: Features a 7mm slot width, perfectly guiding standard 6mm wide GT2 timing belts.
• Secure Dual M4 Locking: Equipped with two M4 set screw holes to lock the pulley firmly onto the shaft.
• Accurate 2mm Pitch: Designed strictly to the GT2 standard for linear motion applications, minimizing backlash.

Package Includes:

1 x GT2 80 Teeth Timing Pulley (5mm Bore, 6mm Belt Width)
