Sprocket 10B-2 z=16 with hub, hardened

Product Description

Sprocket 10B-2 z=16, hardened hub

The sprocket 10B-2 presented here is a duplex sprocket with 16 teeth, made with a hardened hub, for a chain with a pitch of 5/8" / 15.875 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

How do you calculate the pitch circle diameter of a sprocket?

The pitch circle diameter (Dp) is, in simplified terms, the line along which the chain rollers roll. It is calculated using the formula: pitch divided by sine (180° / number of teeth).

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.

What causes premature wear of the side faces of the teeth?

This is most often the result of misalignment of the sprockets on the shafts (so-called lateral runout of the drive). The chain does not run straight, and its inner plates catch on the sides of the teeth, wearing them down to bare metal. The system must be realigned immediately.

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?

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