Sprocket 16B-2 z=40 with hub, hardened

Product Description

Sprocket 16B-2 z=40, hardened hub

The sprocket 16B-2 presented here is a duplex sprocket with 40 teeth, made with a hardened hub, for a chain with a pitch of 1" / 25.4 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

What is the relationship between the number of teeth of a sprocket and the rotational speed of the drive?

This is the basic principle of the transmission ratio. If there is a small sprocket on the motor (drive) and a large one on the machine, the machine will turn more slowly but gain proportionally greater torque (force).

Why are cast sprockets less precise than turned and milled ones?

Cheap castings have a rough tooth surface, hidden air bubbles and slight deformations. CNC-turned and milled sprockets mean a smooth working surface, perfect alignment and safety for the most expensive machines.

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.

Is a duplex sprocket the same as a tandem sprocket (for two single chains)?

No, even though they look very similar. A tandem sprocket is also a single, monolithic sprocket, but with a different (wider) spacing of the toothed rims - designed specifically for two independent simplex chains running in parallel. This duplex sprocket has a rim spacing matched to a single duplex chain, in which both strands are integrated with each other. Using a duplex sprocket for two single chains is a mistake - the spacing is too narrow and the chains will rub against each other, which leads to accelerated wear and, in extreme cases, to serious drive failure.

Where is this product used?

16B-2 sprockets operate in the drives of construction machinery, goods lifts, aggregate conveyors and woodworking machines - wherever tooth durability under heavy load matters.
