Simplex sprocket 28B-1 with hub, 50 teeth - designed for chain with a pitch of 1 3/4" (44.45 mm).

Technical data

Frequently asked questions

Does the difference in hardness between sprocket and chain affect their rate of wear?

Yes - chain and sprocket manufacturers select hardness so that they wear as evenly as possible, rather than one element "cutting down" the other. An excessively hard sprocket working with a soft, non-certified chain (or vice versa) leads to faster wear of the weaker element.

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.

Is it possible to order a single trial piece of the sprocket before placing a larger order?

Yes, catalogue items can be ordered in any quantity, including a single piece for testing or verification before a larger series order.

Can I replace a simplex sprocket with a duplex one without changing the other drive components?

No - switching to a duplex chain and sprocket requires replacing the entire set (the sprockets on both sides of the drive and the chain) with a duplex version of the same pitch, because the rim spacing and chain width differ from those of the simplex version.

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.
