Sprocket 12B-1 z=37 with hub, hardened

Product Description

Sprocket 12B-1 z=37, hardened hub

Sprocket 12B-1 (pitch 3/4" - 19.05 mm), simplex, 37 teeth, with hardened hub. As a European manufacturer, Ozdowski supplies the sprocket in C45E steel (EN 10083-1), in accordance with DIN 8187 / ISO 606 - the teeth are induction hardened (45-55 HRC), while the hub remains soft and easy to machine.

Technical data

Frequently asked questions

Why are cast sprockets less precise than turned and milled ones?

Cheap castings have a rough tooth surface, hidden air bubbles and slight deformations. CNC-turned and milled sprockets mean a smooth working surface, perfect alignment and safety for the most expensive machines.

How does uneven tooth wear affect machine vibration?

Worn teeth cause the so-called polygon effect - the chain drops off and climbs onto the teeth abruptly, which transmits vibrations to the shafts, destroys the bearings and leads to cracking of welds in the machine.

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.

When should I choose a sprocket with hub and when a flat one (plate wheel)?

Flat sprockets (plate wheels) are most often used where they are mounted onto an existing flange or drum, or when there is extremely little space on the shaft. We choose a sprocket with hub when it must reliably transmit high torque directly from the shaft via a key - the hub provides a longer contact surface.

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.
