Sprocket 16B-1 z=28 with hub

Product Description

Sprocket 16B-1 z=28, with hub

Sprocket 16B-1 (pitch 1" - 25.4 mm), simplex, 28 teeth, with hub. The sprocket complies with DIN 8187 / ISO 606 and is made of C45E steel (EN 10083-1); the teeth are not hardened, which lowers the cost of the sprocket and makes it easier to machine (e.g. deep boring of the hub) throughout the entire volume of the material.

Technical data

Frequently asked questions

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.

Does a larger number of teeth always mean a longer service life for the sprocket?

Largely yes - the more teeth are engaged, the lower the load on each individual tooth, and the chain runs over a larger wrap angle, which reduces dynamic impacts. Very small sprockets (with fewer than fifteen or so teeth) wear the fastest and are best avoided if the drive design allows.

Can a sprocket with a technological bore be installed without additional machining?

No - the technological bore is deliberately too small to fit a typical shaft. It must be bored on a lathe to the required diameter and, if necessary, a keyway cut according to the requirements of the specific machine.

What does the marking "z=X" on a sprocket mean and why is it so important when ordering?

"z" is the number of teeth of the sprocket - together with the pitch and the number of chain strands, it unambiguously defines the sprocket geometry (pitch circle and outside diameter). Ordering a sprocket with the wrong "z" usually means that it will not work correctly with the second sprocket already in the machine, and a different transmission ratio than intended will result.

Where is this product used?

16B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
