2 Meter GT2 Timing Belt and 2pcs 16-Teeth 5mm Bore GT2 Pulley Kit for 3D Printers & CNC

Overview

Eliminate transmission backlash and achieve razor-sharp positional tracking with our GT2 Timing Belt and Pulley Combo Kit. This high-performance hardware package includes 2 meters of open-ended GT2 rubber belt and two matching 16-teeth aluminum drive pulleys with a 5mm internal bore. Specially optimized for high-acceleration linear motion, this tooth-profile ecosystem ensures a slip-free mechanical link between your NEMA 17 stepper motors and the printer gantry or CNC slider carriage.

Key Features

• Fiberglass Reinforced Core: The 2-meter rubber belt features internal fiberglass tensile cords, preventing stretching, elongation, and structural wear under heavy loads.

• True GT2 Trapezoidal Tooth Profile: The precision-machined 16-teeth pulleys feature deep, rounded grooves that securely seat the belt teeth, drastically lowering mechanical backlash and printing artifacts.

• Precision 5mm Bore: Designed to slide perfectly onto standard 5mm motor output shafts (such as NEMA 17 stepper motors), secured firmly via two integrated grub screws.

• All-In-One Upgrade Pack: Eliminates compatibility guesswork by packaging the matching belt width and pulley pitch together in one budget-friendly bundle.
