Sprocket 12B-1 z=36 with hub

Product Description

Sprocket 12B-1 z=36, with hub

Sprocket 12B-1 with hub, 36 teeth, simplex - a product matched to chain with a pitch of 19.05 mm (3/4"). 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

When does tooth wear (the "shark fin" profile) mean the sprocket must be replaced?

If the teeth resemble pointed, tilted shark fins, the sprocket must be replaced immediately. Operating on such a profile can damage even a brand-new chain within a dozen or so days.

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.

Do a newly fitted chain and sprocket require running-in after installation?

After installation, it is worth running the drive for a while without full load, observing the smoothness of operation and the bearing temperature - this allows installation errors (e.g. misalignment) to be detected before full load is applied. The tooth profile of the sprocket itself does not require running-in if the sprocket and chain have matching pitch and are made in accordance with the standard.

Can a new chain be fitted on an old, worn sprocket?

Never do this. An old, deformed sprocket has altered tooth geometry and will force drastic mechanical stretching on the new chain. The rule is "new chain - new sprocket" - only then will the drive achieve maximum service life.

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.
