Sprocket 12B-1 z=44 with hub

Product Description

Sprocket 12B-1 z=44, with hub

Simplex sprocket 12B-1 with hub, 44 teeth - designed for chain with a pitch of 3/4" (19.05 mm). Manufactured in accordance with DIN 8187 / ISO 606 from C45E structural steel (EN 10083-1), without tooth hardening - as a Polish manufacturer, Ozdowski supplies an economical version that is fully dimensionally interchangeable with the hardened variant of the same pitch.

Technical data

Frequently asked questions

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).

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.

When is it worth considering a sprocket made of reinforced steel for heavy-duty operating conditions?

In heavy dust, with powerful jerks (e.g. in presses) and wherever a breakdown in the middle of the season is not an option, sprockets made of higher-strength quenching and tempering steel or a variant with hardened teeth are often a good solution - it is worth consulting the supplier in the case of unusual operating conditions.

What does the pitch of a sprocket mean and how can it be checked?

The pitch of a sprocket corresponds to the chain pitch - it is the theoretical distance between the centres of adjacent teeth on the pitch circle. The easiest way to check it is to place a section of matching chain on the sprocket - it should sit perfectly, without tension.

Where is this product used?

Typical applications of the 12B-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.
