Technical data

Frequently asked questions

What should be used to preserve sprockets before a longer break in operation?

After cleaning with a brush and a technical cleaner, apply preservative grease or a thick, moisture-displacing spray oil to the entire surface of the sprocket. This will protect the carbon steel against a rusty film during a break in the workshop.

When does tooth wear (the "shark fin" profile) mean the sprocket must be replaced?

If the teeth resemble pointed, tilted shark fins, the sprocket must be replaced immediately. Operating on such a profile can damage even a brand-new chain within a dozen or so days.

What is a technological bore in a sprocket and why is it left?

We manufacture sprockets with hub with a small, so-called pilot (preliminary) bore. We leave it deliberately so that the customer (or workshop) can bore it precisely to the exact shaft size of their machine.

How do you calculate the pitch circle diameter of a sprocket?

The pitch circle diameter (Dp) is, in simplified terms, the line along which the chain rollers roll. It is calculated using the formula: pitch divided by sine (180° / number of teeth).

Where is this product used?

Typical applications of the 08B-1 sprocket: drives for pumps, mixers and industrial fans, as well as control systems for industrial gates and roller shutters, where resistance to continuous operation is required.
