Product Description
Sprocket 08B-1 z=8, hardened hub
Sprocket 08B-1 (pitch 1/2" - 12.7 mm), simplex, 8 teeth, with hardened hub. Sprocket compliant with DIN 8187 / ISO 606, milled from C45E steel (EN 10083-1); the teeth are induction hardened (45-55 HRC), while the core and hub remain soft, allowing the bore to be safely machined to the shaft size.

Frequently asked questions
How does material quality prevent the teeth from "shearing" during sudden machine jerks?
Soft, uncertified sheet metal deforms under a sudden jerk - the teeth bend over. Steel from a certified melt, correctly heat-treated, has a high yield strength and withstands a torque surge without permanent deformation.
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.
What is the relationship between the number of teeth of a sprocket and the rotational speed of the drive?
This is the basic principle of the transmission ratio. If there is a small sprocket on the motor (drive) and a large one on the machine, the machine will turn more slowly but gain proportionally greater torque (force).
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.
Where is this product used?
08B-1 sprockets operate in the drives of construction machinery, goods lifts, aggregate conveyors and woodworking machines - wherever tooth durability under heavy load matters.
