GT2 20 Teeth 8mm Bore Timing Pulley for 6mm Belt

The GT2 20 Teeth 8mm Bore Timing Pulley is a high-precision synchronous drive wheel engineered for smooth and accurate linear motion. Designed specifically for 3D printers, DIY CNC machines, and robotics actuators, this pulley features a 2mm pitch (GT2 standard) that significantly reduces backlash and improves positioning accuracy. With its precise 8mm inner bore, it mounts securely onto stepper motor shafts or linear rods, ensuring reliable power transmission without slippage.

Constructed from high-grade aluminum alloy, this lightweight yet durable pulley is built to withstand continuous operation. It features a flanged design with a 7.3mm wide slot, making it perfectly compatible with standard 6mm wide GT2 timing belts. Equipped with dual M4 grub screw threads, it provides a robust, slip-free lock on flat-sided or round shafts, making it an essential upgrade or replacement part for Ender, RepRap, and custom coreXY builds.

Features:

• High-Quality Aluminum Construction: Lightweight, durable, and highly resistant to wear and corrosion.
• Precise 20-Tooth Profile: Ensures a perfect grip on GT2 belts to eliminate backlash and slippage.
• 8mm Inner Bore: Designed for a snug fit on 8mm stepper motor shafts and linear rods.
• Dual M4 Grub Screws: Provides a secure, balanced, and slip-free connection to the drive shaft.
• Optimized for 6mm Belts: Flanged guide walls with a 7.3mm inner width keep standard 6mm timing belts perfectly aligned.
