Detail Information

About 16B Double Single Sprockets

A 16B double single sprocket carries two separate simplex 16B chains on one hub. You specify it when a conveyor, screen, or transfer table has two chain tracks that must run parallel but be tensioned, timed, or spaced independently—something a duplex sprocket cannot do.

Compared with using two separate single sprockets, the double single keeps everything on one keyway and one bearing span. That removes a whole class of alignment error and shortens the axial stack.

Sprocket Material, Tooth Hardening, and Finish

The standard build is C45 / AISI 1045 with induction-hardened teeth. The hardening is deliberately shallow and local: the tooth flanks reach roughly 45–55 HRC, so they resist roller impact and the "hooking" that destroys engagement, while the plate stays tough enough to survive shock loads without cracking.

That combination matters more than the headline hardness number. A sprocket that is hard all the way through becomes brittle; a sprocket that is soft everywhere wears into a hook within a season and then starts eating chains. Hardened teeth mated to a standard chain is the correct pairing — put a new chain on a soft sprocket and the wear simply moves into the chain, which is the more expensive half of the system.

Options we regularly supply:

✔ Grey or ductile cast iron for larger diameters and for damping in reversing drives;

✔ 304 / 316 stainless for washdown, food contact and corrosive atmospheres;

✔ Black oxide, nickel or oiled finish for storage and mild corrosion resistance;

✔ Different tooth counts on the two rows, or an axial offset between rows, made to drawing.

16B vs ANSI 80: Why They Are Not Interchangeable

Both chains have a 1-inch pitch, but they are not the same. 16B is the European B-series chain to ISO 606 / DIN 8187; ANSI 80 is the American series. The B-series chain is wider between the inner plates; the roller and plate thickness differ, and the sprocket tooth space is cut to suit.

Running ANSI 80 chain on a 16B sprocket, or the reverse, produces side wear on the inner plates, noisy engagement, a chain that tries to climb the tooth, and premature failure of both parts. If you are replacing a European machine's sprocket, confirm the chain standard before ordering — "1 inch pitch" is not enough information.

The same part is sold under several names: **16B double single**, **2 × 16B-1**, **16B-1 × 2**, **double simplex 16B**. A "16B-2 plate wheel" is a duplex sprocket and is a different part. Double-pitch chain (2082 and similar) is a third, unrelated option.

When the Sprocket Has to Be Replaced

Sprockets rarely fail suddenly; they tell you first:

• the tooth profile is hooked or sharpened at the pitch line;

• the chain sits high in the tooth seat or rides up the flank under load;

• there is a visible step where the rollers contact the tooth;

• noise and vibration appear at a speed where the drive used to run quietly.

Once the teeth are hooked, a new chain will not fix the drive — it will wear into the old profile within weeks. Replace the sprocket and chain as a set, and check both rows: on a double single, it is common for one side to be worn out while the other still looks serviceable, which is itself a sign that the tensioning is unbalanced.

FAQs

Is a 16B double single sprocket the same as a 16B-2 duplex sprocket?

No. A duplex sprocket drives one chain with two rows of rollers joined by common pins. A double single sprocket carries two separate simplex chains on two independent tooth rows, so each chain can be tensioned and replaced on its own.

Can the two rows have different tooth counts?

Yes, made to order. It is a common request when the two chains run at slightly different speeds or when one track drives an auxiliary shaft. Tell us the tooth count for each row.

What is the usual lead time?

Standard sizes ship from stock in small quantities; hardened or custom-tooth-count sprockets are typically made in 2–4 weeks depending on quantity.
