Sprocket 12B-3 z=60 with hub

Product Description

Sprocket 12B-3 z=60, with hub

Sprocket 12B-3 with hub, 60 teeth, triplex (three-strand) - a product matched to chain with a pitch of 19.05 mm (3/4"). The material is C45E carbon steel (EN 10083-1), and the teeth remain unhardened (without induction hardening) - in accordance with DIN 8187 / ISO 606; this version is easier to machine over the entire depth of the sprocket.

Technical data

Frequently asked questions

How do you select a sprocket when the machine lacks space for a larger pitch?

In such a situation, a better solution than increasing the pitch is often to use a multi-strand chain and sprocket of the same (smaller) pitch - several strands together carry a greater load without increasing the sprocket diameter.

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.

How should a chain drive be lubricated to extend its service life?

The lubricant should get between the rollers and plates of the chain, not just onto its outer surface - it is best applied to the lower (slack) part of the chain, just before it runs onto the sprocket. In a dusty environment, a thick grease works better, while at high speeds a lower-viscosity oil that penetrates the joints more easily is preferable.

Where is this product used?

12B-3 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
