Sprocket 08B-3 z=26 with hub

Product Description

Sprocket 08B-3 z=26, with hub

Sprocket 08B-3, triplex (three-strand), with 26 teeth and a hub - pitch 1/2" (12.7 mm). As a European manufacturer, Ozdowski supplies the sprocket in C45E steel (EN 10083-1), in accordance with DIN 8187 / ISO 606 - a version without tooth hardening, cheaper than the hardened variant and sufficient for many typical industrial applications.

Technical data

Frequently asked questions

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 can you recognise an idler sprocket bearing that is starting to wear before it fails?

The first symptom is usually increased noise and noticeable, excessive play of the sprocket when it is moved by hand with the machine stopped. It is also worth periodically checking the temperature of the bearing housing during operation - an increase compared with other bearings in the system signals progressive wear.

Can a sprocket be reconditioned, e.g. by hardfacing worn teeth?

Technically, hardfacing and re-milling the teeth is possible, but in practice it is rarely cost-effective - the cost of reconditioning is often close to the price of a new sprocket, and restoring the full precision of the tooth profile requires specialist machining. In most cases, replacing it with a new sprocket is the quicker and safer solution.

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.

Where is this product used?

Typical applications of the 08B-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.
