Product Description
Sprocket 16B-1 z=39, hardened hub
Sprocket 16B-1 with hardened hub, 39 teeth, simplex - a product matched to chain with a pitch of 25.4 mm (1"). 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
How do you cut a keyway in the hub of a sprocket?
We cut keyways precisely on slotting machines according to DIN 6885. If you do it yourself, maintain axial alignment and the correct width and depth of the keyway so that the key sits securely and is not sheared off.
Why are cast sprockets less precise than turned and milled ones?
Cheap castings have a rough tooth surface, hidden air bubbles and slight deformations. CNC-turned and milled sprockets mean a smooth working surface, perfect alignment and safety for the most expensive machines.
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.
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?
Typical applications of the 16B-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.
