Sprocket 32B-1 z=26 with hub

Product Description

Sprocket 32B-1 z=26, with hub

Sprocket 32B-1, simplex, with 26 teeth and a hub - pitch 2" (50.8 mm). The material is C45E carbon steel (EN 10083-1), and the teeth remain unhardened (without induction hardening) - in accordance with DIN 8187 / ISO 606; this version is easier to machine over the entire depth of the sprocket.

Technical data

Frequently asked questions

How can you recognise a sprocket not made in accordance with the DIN 8187 profile?

Most often it is visible from the incorrect seating of the chain on the teeth - the chain "sits" on the tooth tips or too deep in the tooth roots, despite the correct pitch. In that case, it is worth placing a section of a known reference chain of this pitch on the sprocket and checking whether it engages each tooth evenly and smoothly.

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.

Can the hub of a sprocket have a different hardness from the toothed rim?

Yes, and in practice this is usually the case - in the version with induction-hardened teeth, only the toothed rim is hardened, while the hub remains soft so that it can be freely turned and a keyway can be cut in it. This solution combines tooth wear resistance with ease of machining the hub.

Does a larger number of teeth always mean a longer service life for the sprocket?

Largely yes - the more teeth are engaged, the lower the load on each individual tooth, and the chain runs over a larger wrap angle, which reduces dynamic impacts. Very small sprockets (with fewer than fifteen or so teeth) wear the fastest and are best avoided if the drive design allows.

Where is this product used?

Typical applications of the 32B-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.
