Product Description
Sprocket 16B-2 z=30, hardened hub
Sprocket 16B-2 with hardened hub, 30 teeth, duplex - a product matched to a chain with a pitch of 25.4 mm (1"). 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.

Frequently asked questions
How do I select a sprocket for a roller chain?
The selected sprocket must match the chain parameters exactly. Pay attention to three things: the standard (European B series), the pitch and the number of strands. The sprocket must have a tooth profile compliant with DIN 8187 so that the chain enters the tooth root smoothly without jamming.
What forces act on the key in a sprocket and how can it be prevented from shearing?
The key transmits the entire shearing torque between the shaft and the sprocket. Make sure it is made of suitable quenched and tempered steel, has an accurate fit in the keyway and that the machine is not subjected to extreme jerks without an overload clutch.
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.
