Product Description
Sprocket 20B-1 z=36, with hub
Sprocket 20B-1, simplex, with 36 teeth and a hub - pitch 1 1/4" (31.75 mm). As a European manufacturer, Ozdowski supplies the sprocket in C45E steel (EN 10083-1), in accordance with DIN 8187 / ISO 606 - a version without tooth hardening, cheaper than the hardened variant and sufficient for many typical industrial applications.

Frequently asked questions
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 is the set screw hole in the hub for?
The threaded hole in the hub is used to screw in a headless screw (a so-called grub screw). It secures the sprocket against axial displacement along the shaft during machine vibration.
How do you select a sprocket when the machine lacks space for a larger pitch?
In such a situation, a better solution than increasing the pitch is often to use a multi-strand chain and sprocket of the same (smaller) pitch - several strands together carry a greater load without increasing the sprocket diameter.
How do you correctly align sprockets during installation?
The driving and driven sprockets must be in one perfect line. You can use a long steel straightedge placed against the faces of both sprockets or a professional laser alignment tool. Even a slight angular deviation will quickly destroy the chain.
Where is this product used?
20B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
