Applications:
This 45-tooth sprocket is ideal for lower-speed, high-torque drive systems where maximum load transmission and power delivery are required. It's commonly used in heavy-duty conveyor systems, industrial machinery drives, agricultural equipment, and demanding mechanical applications where consistent and reliable power transmission is essential.
The larger tooth count and substantial boss diameter of 90mm make this sprocket particularly suited for applications requiring significant torque multiplication and smooth operation at reduced speeds. The pilot bore design allows for flexible shaft mounting options, making it adaptable to various installation configurations.
As part of our extensive range of 08B1 simplex chain sprockets, this sprocket offers the quality and precision engineering you need for dependable operation in your heavy-duty application.
