Product Description
Sprocket 12B-1 z=57, with hub
Sprocket 12B-1 with hub, 57 teeth, simplex - a product matched to chain with a pitch of 19.05 mm (3/4"). Compliance with DIN 8187 / ISO 606 guarantees full interchangeability with a chain of the same pitch; the sprocket is made of C45E steel (EN 10083-1) in a non-hardened version - the standard choice for applications with moderate and medium load.

Frequently asked questions
In what cases are multi-strand sprockets used?
They are used to drive multi-strand chains in heavily loaded machines where there is no room for a wider sprocket with a larger pitch. Several strands distribute the load evenly, preventing premature chain breakage.
How do you select the number of teeth on the driving and driven sprockets to obtain the required ratio?
The ratio is calculated as the quotient of the number of teeth on the driven sprocket and the number of teeth on the driving sprocket. For example, to halve the rotational speed, the driven sprocket should have twice as many teeth as the driving sprocket - both sprockets must have the same pitch and number of strands.
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.
How can a sprocket and chain be protected against corrosion during storage?
After cleaning off any dirt, it is advisable to apply a layer of preservative grease or anti-corrosion oil and store the sprocket in a dry place not exposed to condensation. In the steel version (without coating), even a short damp break in the workshop can cause a rusty film on the tooth surfaces.
Where is this product used?
This type of sprocket is used in drives of agricultural and industrial machinery, including screw and bucket conveyors, feed conveyors, packaging machines and internal transport systems.
