Sprocket 12B-1 z=15 with hub, hardened

Product Description

Sprocket 12B-1 z=15, hardened hub

The sprocket 12B-1 shown is a simplex sprocket with 15 teeth, made with a hardened hub, for chain with a pitch of 3/4" / 19.05 mm. The material is carbon steel C45E (EN 10083-1), and the teeth undergo induction hardening to 45-55 HRC - in accordance with DIN 8187 / ISO 606; the hub retains a lower core hardness, so it can be machined safely.

Technical data

Frequently asked questions

When is it worth considering a sprocket made of reinforced steel for heavy-duty operating conditions?

In heavy dust, with powerful jolts (e.g. in presses) and where a breakdown in the middle of the season cannot be afforded, sprockets made of higher-strength quenched and tempered steel are often a good solution - it is worth consulting the supplier about unusual operating conditions.

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 material is this sprocket made of?

As standard, it is carbon steel C45E (EN 10083-1) - a good material for typical industrial applications, providing a good balance between strength and machinability of the hub.

When should I choose a sprocket with hub and when a flat one (plate wheel)?

Flat sprockets (plate wheels) are most often used where they are mounted onto an existing flange or drum, or when there is extremely little space on the shaft. We choose a sprocket with hub when it must reliably transmit high torque directly from the shaft via a key - the hub provides a longer contact surface.

Where is this product used?

12B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
