Technical data

Frequently asked questions

If I order today, when will I receive the product?

Information on the lead time is given next to the product's stock level, above the price. If the sprocket is available in the main warehouse, we ship it no later than the next working day.

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 metal against rust deposits during the break while it is stored in the hall.

Is a sprocket with hub suitable for reversing drives (with a change of rotation direction)?

Yes, the tooth geometry of a sprocket is symmetrical and has no preferred direction of operation, so the sprocket can be used in drives that change direction of rotation. In such systems, correct chain tension on both sides is particularly important, because when reversing, each side alternately becomes the working side.

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.

Where is this product used?

Typical applications of the 12B-3 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.
