Product Description

Sprocket 12B-3 z=95, with hub

Sprocket 12B-3, triplex (three-strand), with 95 teeth and a hub - pitch 3/4" (19.05 mm). Manufactured in accordance with DIN 8187 / ISO 606 from C45E structural steel (EN 10083-1), without tooth hardening - as a Polish manufacturer, Ozdowski supplies an economical version that is fully dimensionally interchangeable with the hardened variant of the same pitch.

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 do I select a sprocket with bearing for a tensioning system?

An idler sprocket (with built-in bearing) is selected according to the pitch of the working chain and mounted on the slack side (not on the tight side). It is important that the bearing is protected against dust, especially in agricultural machinery.

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.

Is it worth using guards on sprockets and the entire drive?

Yes - a guard protects operators from contact with moving parts and at the same time limits the ingress of dust and moisture to the chain, which genuinely extends its service life. In many industrial machines, a chain drive guard is also an occupational safety requirement.

Where is this product used?

12B-3 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
