Product Description
Sprocket 08B-1 z=45, hardened hub
Sprocket 08B-1 with hardened hub, 45 teeth, simplex - a product matched to chain with a pitch of 12.7 mm (1/2"). 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
When does tooth wear (the "shark fin" profile) mean the sprocket must be replaced?
If the teeth resemble pointed, tilted shark fins, the sprocket must be replaced immediately. Operating on such a profile can damage even a brand-new chain within a dozen or so days.
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 you correctly align sprockets during installation?
The driving and driven sprockets must be in one perfect line. You can use a long steel straightedge placed against the faces of both sprockets or a professional laser alignment tool. Even a slight angular deviation will quickly destroy the chain.
What material is this sprocket made of?
As standard, it is carbon steel C45E (EN 10083-1) - a good material for typical industrial applications, providing a good balance between strength and machinability of the hub.
Where is this product used?
Typical applications of the 08B-1 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.
