METRIC & INCH SIZE

Timing belt pulleys are mechanical components used to transmit power and motion between a timing belt and a shaft or pulley. They consist of a toothed belt which meshes with the teeth of the pulley and a hub or flange that attaches to a shaft or pulley. Timing belt pulleys are commonly used in applications where precise timing and synchronization of components is required such as in engines, machine tools and robotics.

Timing belt pulleys are available in both metric and inch sizes, depending on the application requirements. The size of a timing belt pulley is determined by the pitch of the timing belt, which is the distance between the teeth on the belt. The most common pitch sizes for timing belts and pulleys are:

Metric: Metric timing belts and pulleys are commonly used in Europe and other countries that use the metric system. Common pitch sizes for metric timing belts and pulleys include 3mm, 5mm, 8mm and 14mm.
Inch: Inch timing belts and pulleys are commonly used in North America and other countries that use the imperial system. Common pitch sizes for inch timing belts and pulleys include 1/5″, 3/8″, 1/2″ and 3/4″.

Timing belt pulleys are also available in a variety of materials and configurations including:

Steel: Steel timing belt pulleys are durable and can support heavy loads.
Aluminum: Aluminum timing belt pulleys are lightweight and can be used in applications where weight is a concern.
Plastic: Plastic timing belt pulleys are lightweight and can be used in applications where low friction and low noise are important.

Proper selection, installation and maintenance of timing belt pulleys are important to ensure optimal performance and longevity of equipment. Factors to consider when selecting timing belt pulleys include pitch size, number of teeth, bore size and hub or flange configuration.
