Sprocket 16B-2 z=20 with hub, hardened

Product Description

Sprocket 16B-2 z=20, hardened hub

The sprocket 16B-2 presented here is a duplex sprocket with 20 teeth, made with a hardened hub, for a chain with a pitch of 1" / 25.4 mm. Made in accordance with DIN 8187 / ISO 606, from C45E steel (EN 10083-1), with teeth induction hardened to 45-55 HRC - as a Polish manufacturer, Ozdowski ensures that the hub remains soft and suitable for turning.

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.

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).

How do you correctly align sprockets during installation?

The driving and driven sprockets must be in one perfect line. You can use a long steel straightedge placed against the faces of both sprockets or a professional laser alignment tool. Even a slight angular deviation will quickly destroy the chain.

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.
