NACTECH 5M GT2 Timing Belt + GT2 20 Teeth Timing Belt Pulley Wheel 8mm Bore with Wrench and Screws for Anet A8 RepRap Pursa i3 3D Printer CNC Parts

Question: does the belt have fiber inside or isit pure rubber?
Answer: The belt have fiber inside.

Question: What is the best method to join the belt?
One way,Probably best to get a length that works for your application, rather than trying to join them.
Another way, Overlap the ends of the belt and cut the upper end teeth for a perfect fit. Then glue them with glue.
Or put the ends together, stick with a small flexible and sturdy strap.

GT2 belt designed for linear movement, uses profile with rounded teeth so that the belt teeth are inserted
With softness and precision in groove to avoid slipping. The belt can not move in the opposite direction in the groove of the pulley.
The 20-tooth belt has at least six teeth in contact with the pulley, reducing the possibility of slip rings.
In comparison with a 16 tooth belt, there are more contact surfaces and more stable.
Suitable for multi-axis transmission, without lubrication.
Timing belts and pulleys are popular choices for Reprap, Prusa, MendelMax and 3D printer printers.
It is also the perfect accessory for engraving machines, dishwashers, packaging machines, motorcycles, automobiles, dryers,
inkjet printers, conveyors, bonding machines and other small precision mechanical transmissions.
