Sprocket 16B-3 z=17 with hub

Product Description

Sprocket 16B-3 z=17, with hub

Sprocket 16B-3 with hub, 17 teeth, triplex (three-strand) - a product matched to chain with a pitch of 25.4 mm (1"). Compliance with DIN 8187 / ISO 606 guarantees full interchangeability with a chain of the same pitch; the sprocket is made of C45E steel (EN 10083-1) in a non-hardened version - the standard choice for applications with moderate and medium load.

Technical data

Frequently asked questions

How can you check whether the chain in an existing drive is already excessively elongated (stretched)?

Stretch out a section of a dozen or so chain links and compare its length with the catalogue dimension - an elongation of more than approx. 2-3% means the chain is due for replacement. A stretched chain no longer seats properly on the sprocket teeth, which accelerates the wear of both components, so it is better to replace it before it damages the sprocket as well.

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.

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.

Where is this product used?

This type of sprocket is used in drives of agricultural and industrial machinery, including screw and bucket conveyors, feed conveyors, packaging machines and internal transport systems.
