Sprocket 16B-2 z=17 with hub, hardened

Product Description

Sprocket 16B-2 z=17, hardened hub

Sprocket 16B-2 (pitch 1" - 25.4 mm), duplex, 17 teeth, with hardened hub. 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 does material quality prevent the teeth from "shearing" during sudden machine jerks?

Soft, uncertified sheet metal deforms under a sudden jerk - the teeth bend over. Steel from a certified melt, correctly heat-treated, has a high yield strength and withstands a torque surge without permanent deformation.

What is a technological bore in a sprocket and why is it left?

We manufacture sprockets with hub with a small, so-called pilot (preliminary) bore. We leave it deliberately so that the customer (or workshop) can bore it precisely to the exact shaft size of their machine.

How do I select a sprocket with bearing for a tensioning system?

An idler sprocket (with built-in bearing) is selected according to the pitch of the working chain and mounted on the slack side (not on the tight side). It is important that the bearing is protected against dust, especially in agricultural machinery.

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.
