Sprocket 10B-1 z=26 with hub, hardened

Product Description

Sprocket 10B-1 z=26, hardened hub

Sprocket 10B-1, simplex, with 26 teeth and a hardened hub - pitch 5/8" (15.875 mm). Made in accordance with DIN 8187 / ISO 606, from C45E steel (EN 10083-1), with teeth induction hardened to 45-55 HRC - as a Polish manufacturer, Ozdowski ensures that the hub remains soft and suitable for turning.

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.

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.

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.

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.

Where is this product used?

10B-1 sprockets operate in the drives of construction machinery, goods lifts, aggregate conveyors and woodworking machines - wherever tooth durability under heavy load matters.
