GT2 20 Tooth 6.35mm Bore Synchronous Pulley for 10mm Belt

The GT2 20T Synchronous Pulley with a 6.35mm bore is a high-precision aluminum drive pulley designed for 3D printers, CNC machines, and DIY robotics. Engineered specifically for 10mm wide GT2 timing belts, this 20-tooth pulley provides a reliable, slip-free mechanical connection to stepper motors with a 6.35mm (1/4 inch) shaft. It ensures precise linear positioning and minimizes backlash, making it a critical component for high-accuracy motion control projects.

This synchronous pulley is widely used in RepRap 3D printers, laser engravers, and small-scale CNC routers. It is fully compatible with standard 2mm pitch GT2 belts and mounts securely using two M4 grub screws. Its lightweight aluminum alloy construction reduces rotational inertia, allowing your stepper motors to achieve higher acceleration and smoother speed transitions in demanding applications.

Features:

• High-Grade Aluminum: Manufactured from durable, lightweight aluminum alloy for low rotational inertia and long-lasting performance.
• Precise 20-Tooth Profile: Designed with a 2mm pitch (GT2/2GT standard) to prevent belt slippage and ensure accurate linear motion.
• 6.35mm Bore Size: Perfect fit for stepper motors with 6.35mm (1/4") shafts, commonly found on high-torque NEMA 17 and NEMA 23 motors.
• 10mm Belt Compatibility: Features a wide channel optimized for 10mm wide timing belts, providing higher load capacity than standard 6mm belts.
• Secure Dual M4 Fastening: Equipped with two M4 set screw holes to lock the pulley firmly onto the motor shaft, preventing axial and rotational slippage.

Package Includes:

1 x GT2 20T Synchronous Pulley (6.35mm Bore, 10mm Belt Width)
