Introduction to Timing Pulley 8mm Bore 20 Teeth

Timing pulleys with 8mm bore and 20 teeth are metal pulleys designed for a wide range of power transmission applications. They are usually made from steel, aluminum alloy, or stainless steel and feature a toothed belt drive system. Timing pulleys are used to transfer mechanical power between two parallel shafts and are typically equipped with grooves that mesh with a timing belt to ensure the synchronization of two shafts for smooth and efficient operation.

Product Selection

When selecting a timing pulley, there are several criteria to consider, including standards, tooth shape, installation holes, and material.


Timing pulleys can be made according to international standards, such as the American Standard (ANSI) and the European Standard (DIN). The main differences between the two standards are the number of grooves, the shape of the grooves, the distance between the grooves, and the type of belt used.

Tooth Shape

Timing pulleys come in a variety of tooth shapes, including standard, special, and curved. Standard tooth shape is the most common, while special tooth shape is designed to reduce noise and vibration. Curved tooth shape is suitable for high-speed applications.

Installation Holes

Timing pulleys may have different types of installation holes, such as pilot bolts, tap bolts, QD bolts, etc. The type of installation holes depends on the application and the associated power transmission requirement.


Timing pulleys can be made from aluminum alloy, steel, or stainless steel depending on the application and the power transmission requirement.

Installation, Disassembly and Maintenance

Installing, disassembling and maintaining timing pulleys is relatively simple. Timing pulleys should be installed with the grooves facing the direction of rotation. When disassembling, the timing belt should be removed first and then the timing pulley can be easily removed from the shaft. For maintenance, the pulley should be inspected regularly to ensure that the grooves are free of debris and that the belt is in good condition. Timing belts should also be replaced regularly to ensure smooth operation.
