Product Description

Sprocket 12B-3 z=33, with hub

Sprocket 12B-3, triplex (three-strand), with 33 teeth and a hub - pitch 3/4" (19.05 mm). 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.

Technical data

Frequently asked questions

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.

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.

How do I select a sprocket for a roller chain?

The selected sprocket must match the chain parameters exactly. Pay attention to three things: the standard (European B series), the pitch and the number of strands. The sprocket must have a tooth profile compliant with DIN 8187 so that the chain enters the tooth root smoothly without jamming.

Does a sprocket with hub have a fixed mounting side, or can it be reversed?

The sprocket is usually symmetrical with respect to the plane of the rim, so the rim itself cannot be "reversed incorrectly" - but the hub is usually on only one side of the sprocket, which determines which way the sprocket must be mounted relative to other components on the shaft (e.g. bearings, other sprockets).

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.

When placing your order, please check the current stock level of this gear - the lead time depends on it and is clearly stated according to the quantity available in the given warehouse.
