4.5MM Pitch (synchronous belts
) is one type of many other configurations of metric pitch timing belts. In timing pulleys
, the key focus is applied to the speed ratio maintenance in the transmission power, and these types of belts are used in timing pulleys that have the same pitch designated in millimeters for synchronous belt drive systems. Timing pulleys have a reputation for durability, efficiency, and a wide variety of application areas. The pitch refers to the distance of the center of one tooth to the center of the next tooth, and 4.5MM Pitch (synchronous belts) have a distance of 4.5mm between their adjacent tooth centers. 4mm pitch belts have various choices for pitch design, including AT pitch, GT pitch HDT pitch, T-pitch, and super torque pitch. Synchronous belts fit in sheaved grooves in timing pulleys tat have equally spaced grooves which correspond to the pitch of the belts. 4.5MM Pitch (synchronous belts) can be used in automobile engines, treadmills, and sewing machines.
