Accurate timing ensures that the valves open and close in harmony with the piston movements. If the timing is off—either due to a worn-out belt or improper installation—serious engine problems can arise. An out-of-sync engine might experience misfires, loss of power, or even catastrophic failure, such as valve-to-piston contact in interference engines.

2. Narrow V-Belts These belts have a narrower cross-section compared to classical V-belts, allowing for tighter bends and a smaller sheave diameter. They are often used in applications where space is limited, offering higher efficiency due to less slippage. The narrow design increases the contact area with the pulley, enhancing power transmission.

- Mid-Range ($75 - $150) This price range generally includes good-quality leather belts with better durability and style. They are suitable for both casual and semi-formal occasions.

In 3D printers, timing belts are primarily used in the motion system that drives the print head and the print bed. Specifically, they are responsible for the x and y-axis movements, crucial for the accurate placement of filament during the printing process.
