Metric & inch size

Timing belt pulleys are available in 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. Standard 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. Standard 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.
Aluminium: Aluminum timing belt pulleys are lightweight and can be used in applications where weight is a concern.
Plastic: These timing belt pulleys are lightweight and can be used in applications where low friction and noise are essential.

Proper selection, installation, and maintenance of timing belt pulleys are essential 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.
