Sprocket 20B-1 z=10 with hub

Product Description

Sprocket 20B-1 z=10, with hub

Sprocket 20B-1 (pitch 1 1/4" - 31.75 mm), simplex, 10 teeth, with hub. The sprocket complies with DIN 8187 / ISO 606 and is made of C45E steel (EN 10083-1); the teeth are not hardened, which lowers the cost of the sprocket and makes it easier to machine (e.g. deep boring of the hub) throughout the entire volume of the material.

Technical data

Frequently asked questions

When is it worth using a clamping bush (Taper Bush) for a sprocket?

Wherever fast assembly matters. A clamping bush eliminates the need for laborious boring of the hub and cutting of a keyway - you insert the sprocket, tighten the screws and the machine is back in operation within minutes.

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 metal against rust deposits during the break while it is stored in the hall.

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.

How do sprockets for roller chains differ from sprockets for toothed chains (silent chain)?

A sprocket for roller chain has a rounded tooth root matched to the chain roller (profile according to DIN 8187), whereas a sprocket for toothed chain (silent chain) has a flat, trapezoidal tooth profile that engages the chain plates instead of rollers. These two systems are not interchangeable.

Where is this product used?

20B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
