Sprocket 16B-1 z=24 with hub

Product Description

Sprocket 16B-1 z=24, with hub

Simplex sprocket 16B-1 with hub, 24 teeth - designed for chain with a pitch of 1" (25.4 mm). 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

Can a sprocket be reconditioned, e.g. by hardfacing worn teeth?

Technically, hardfacing and re-milling the teeth is possible, but in practice it is rarely cost-effective - the cost of reconditioning is often close to the price of a new sprocket, and restoring the full precision of the tooth profile requires specialist machining. In most cases, replacing it with a new sprocket is the quicker and safer solution.

Do I need to select dedicated bearings for a sprocket with hub?

A sprocket with hub mounted with a key does not require its own bearings - the load is carried by the bearings of the shaft on which the sprocket is mounted. A dedicated bearing built into the sprocket is only needed for tensioning or guide sprockets mounted on an axle without its own drive.

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.

What does the marking "z=X" on a sprocket mean and why is it so important when ordering?

"z" is the number of teeth of the sprocket - together with the pitch and the number of chain strands, it unambiguously defines the sprocket geometry (pitch circle and outside diameter). Ordering a sprocket with the wrong "z" usually means that it will not work correctly with the second sprocket already in the machine, and a different transmission ratio than intended will result.

Where is this product used?

Applications include drives in the food industry, packaging machines, sorting lines and agricultural harvesting machines, where the sprocket operates seasonally but under full load.
