Description
Toothless GT2 Idler Pulley 5mm Bore for 3D Printer (Bore 5mm, Toothless) in pakisan
The Toothless GT2 Idler Pulley 5mm Bore is a mechanical accessory used to guide and support timing belts in belt-driven motion systems. Unlike a toothed drive pulley, this idler pulley has a smooth running surface and does not directly drive the belt through matching teeth.
It is commonly used in 3D printer assemblies to guide the GT2 timing belt around corners, maintain the belt path and support proper belt tension. The 5mm bore allows installation on compatible 5mm shafts or mounting hardware.
This component is suitable for RepRap 3D printers, DIY CNC machines, laser engravers and other belt-driven mechanical projects.

Installation / Setup
-
Check that the pulley has a 5mm bore suitable for your mounting shaft.
-
Confirm that its width matches your GT2 timing belt.
-
Install the pulley using compatible mounting hardware.
-
Position it along the intended belt path.
-
Ensure the pulley rotates freely without excessive friction.
-
Align the pulley with the drive pulley and other belt-guiding components.
-
Adjust belt tension according to your machine’s requirements.
Precautions
-
Confirm the pulley dimensions before installation.
-
Do not assume every 5mm-bore pulley has the same width or outer diameter.
-
Ensure the pulley is aligned with the timing belt.
-
Avoid excessive belt tension.
-
Check that the pulley rotates smoothly.
-
Inspect the mounting shaft and bearing arrangement for wear.
-
Replace damaged or rough-running pulleys to prevent belt wear.
