Sprocket 10B-2 z=15 with hub, hardened

Product Description

Sprocket 10B-2 z=15, hardened hub

Sprocket 10B-2 with hardened hub, 15 teeth, duplex - a product matched to a chain with a pitch of 15.875 mm (5/8"). 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

How does a hardness of around 45-55 HRC on the teeth extend the service life of the sprocket-chain system?

A hardness of 45-55 HRC matched to the hardened chain rollers is the optimal combination. The sprocket and chain wear slowly and evenly, and the sprocket does not turn into a "blade" that could shear the chain during operation.

What is a technological bore in a sprocket and why is it left?

We manufacture sprockets with hub with a small, so-called pilot (preliminary) bore. We leave it deliberately so that the customer (or workshop) can bore it precisely to the exact shaft size of their 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.

Is a duplex sprocket the same as a tandem sprocket (for two single chains)?

No, even though they look very similar. A tandem sprocket is also a single, monolithic sprocket, but with a different (wider) spacing of the toothed rims - designed specifically for two independent simplex chains running in parallel. This duplex sprocket has a rim spacing matched to a single duplex chain, in which both strands are integrated with each other. Using a duplex sprocket for two single chains is a mistake - the spacing is too narrow and the chains will rub against each other, which leads to accelerated wear and, in extreme cases, to serious drive failure.

Where is this product used?

10B-2 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
