Sprocket 24B-1 z=27 with hub, hardened

Product Description

Sprocket 24B-1 z=27, hardened hub

Sprocket 24B-1 (pitch 1 1/2" - 38.1 mm), simplex, 27 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

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.

In what cases are multi-strand sprockets used?

They are used to drive multi-strand chains in heavily loaded machines where there is no room for a wider sprocket with a larger pitch. Several strands distribute the load evenly, preventing premature chain breakage.

How does induction hardening of the teeth affect abrasion resistance?

Induction hardening hardens only the surface layer of the tooth, where the chain rollers bear. The tooth is resistant to wear, while the sprocket core and hub remain elastic enough to safely absorb impacts and be suitable for boring.

What should be used to preserve sprockets before a longer break in operation?

After cleaning with a brush and a technical cleaner, apply preservative grease or a thick, moisture-displacing spray oil to the entire surface of the sprocket. This will protect the carbon steel against a rusty film during a break in the workshop.

Where is this product used?

Typical applications of the 24B-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.
