Product Description
Sprocket 16B-1 z=40, hardened hub
Sprocket 16B-1 (pitch 1" - 25.4 mm), simplex, 40 teeth, with hardened hub. Compliance with DIN 8187 / ISO 606 guarantees full interchangeability with chain of the same pitch; C45E steel (EN 10083-1) and induction hardening of the teeth (45-55 HRC) provide high wear resistance while keeping the hub machinable.

Frequently asked questions
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 check the radial and axial runout of a sprocket after mounting it on the shaft?
A dial indicator on a magnetic stand is used for the measurement. Place the tip against the circumference of the sprocket or its side face, rotate the shaft and check the deviations. Excessive runout indicates faulty installation or a damaged shaft.
How does a hardness of around 45-55 HRC on the teeth extend the service life of the sprocket-chain system?
A hardness of 45-55 HRC matched to the hardened chain rollers is the optimal combination. The sprocket and chain wear slowly and evenly, and the sprocket does not turn into a "blade" that could shear the chain during operation.
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?
16B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
