Product Description
Sprocket 08B-1 z=29, hardened hub
Sprocket 08B-1 (pitch 1/2" - 12.7 mm), simplex, 29 teeth, with hardened hub. The material is carbon steel C45E (EN 10083-1), and the teeth undergo induction hardening to 45-55 HRC - in accordance with DIN 8187 / ISO 606; the hub retains a lower core hardness, so it can be machined safely.

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.
When is it worth using a clamping bush (Taper Bush) for a sprocket?
Wherever fast assembly matters. A clamping bush eliminates the need for laborious boring of the hub and cutting of a keyway - you insert the sprocket, tighten the screws and the machine is back in operation within minutes.
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.
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.
Where is this product used?
Applications include drives in the food industry, packaging machines, sorting lines and agricultural harvesting machines, where the sprocket operates seasonally but under full load.
