Selling the Most Complete & Best Quality Sprockets
The sprocket is a sturdy wheel with teeth that lock the chain. As the sprocket rotates, the teeth will hold the chain and move other parts that are interlocked with the chain. This series of sequential operations allows for simple and controlled rotational movement of larger equipment and machines. Sprockets are often made of metal or reinforced plastic that can withstand the driving forces of the chain. These components are often compared to gears, which have a wheel-shaped design similar to gears. Unlike gears — which are interlocked to transfer rotational motion — sprockets only interact directly with different types of chains. Rather than a gear system, most sprockets and chain systems work in a similar way to bicycle chain assemblies — which are lightweight sprockets and chain assemblies.
Sprockets are highly specialized parts made to fit a specific chain and handle a specific load. Sprockets must meet strict specifications regarding factors such as:
- Size
- Dimension
- Diameter
- Tooth width and depth
Sprocket Types
Different types of sprockets have different hubs. The hub is the additional thickness around the center plate of the sprocket that does not include the teeth. There are four main types of sprockets defined by the American National Standards Institute (ANSI):
- Type A sprocket, which is just a plate with no additional thickness or hub.
- Type B sprocket, which has a hub on one side.
- Type C sprocket, which has a hub of equal thickness on both sides of the plate.
- Type C offset or Type D Sprocket, which also has two hubs. However, each hub has a different thickness which makes the sprocket asymmetrical.
Different types allow different applications. Type A and B sprockets fit perfectly into equipment, for example, while Type C sprockets are generally larger and require more thickness to support the weight.
