Main motor belts are often made from durable materials such as rubber or other synthetic compounds. The main motor belts are part of the drive system that connects the main motor to different components of the printing press. This includes transferring power to rollers, cylinders, and other moving parts essential for the printing process. Proper tension and alignment of the main motor belts are critical for maintaining consistent and accurate printing. Tensioning systems and alignment mechanisms are employed to ensure the belts stay in place and function smoothly. The size and specifications of the main motor belts are determined by the design and requirements of the specific printing press model. They must be compatible with the power and torque demands of the main motor.
