A few notes about SFAT10 toothed belt installation, there are these suggestions over here, hopefully it can solve your problem.

SFAT10 toothed belt is a product made of PU material. With special tooth design, it is widely used in various industrial machines and can withstand high strength and high speed working environment. It is characterized by straight line operation, which reduces the chance of product deviation in industrial production. SFAT10 toothed belt has many applications in life. It can be used in industrial machinery such as automation equipment, machine assembly lines and production lines. Because it can adapt to the characteristics of high strength and high speed, it can withstand long working hours and is not easy to wear and break, and regular product maintenance can improve the service life and stability of mechanical equipment.

SFAT10 pu timing belt, is a timing belt made of polyurethane material. This belt has good anti-friction and anti-stretching properties, it is not easy to age and break. In contrast to conventional belts, the SFAT10 pu timing belt utilizes the SFAT tooth design, which produces a product with a half tooth misalignment. This design allows the belt to automatically move forward in a straight line in conjunction with the gears, reducing the possibility of deflection
