Sprocket 10B-1 z=21 with hub, hardened

Product Description

Sprocket 10B-1 z=21, hardened hub

Sprocket 10B-1 (pitch 5/8" - 15.875 mm), simplex, 21 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.

Technical data

Frequently asked questions

What is the set screw hole in the hub for?

The threaded hole in the hub is used to screw in a headless screw (a so-called grub screw). It secures the sprocket against axial displacement along the shaft during machine vibration.

Can a new chain be fitted on an old, worn sprocket?

Never do this. An old, deformed sprocket has altered tooth geometry and will force drastic mechanical stretching on the new chain. The rule is "new chain - new sprocket" - only then will the drive achieve maximum service life.

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.

Can a sprocket be welded directly to the drive shaft?

Technically this is possible, but we strongly advise against such a solution. Welding overheats the material, damages nearby bearings, bends the shaft and prevents the worn sprocket from being easily replaced later. Always use mounting with a key or a clamping bush.

Where is this product used?

This type of sprocket is used in drives of agricultural and industrial machinery, including screw and bucket conveyors, feed conveyors, packaging machines and internal transport systems.
