Product Description

Sprocket 10A-2 (50-2) z=16 with hub works with ASA 50 (10A-2) roller chain, double-strand (duplex), with a pitch of 15.875 mm (5/8"). It has 16 teeth and is made of C45 steel in accordance with ISO 606 and ANSI B29.1.

The sprocket has a one-sided hub with a diameter of 64 mm and a pilot bore of Ø16 mm, which is bored to the shaft size and completed with a keyway or a set screw hole. The total width of the sprocket is 45 mm.

Technical data

Applications

It works well in roller and belt conveyor drives and on packaging lines. The double-strand version carries higher loads than a single-strand one of the same pitch, so it is chosen where there is no room for a chain with a larger pitch.

Frequently asked questions

Which chain does this sprocket fit?

ASA 50-2 (10A-2) roller chain with a pitch of 15.875 mm. A duplex sprocket requires a double-strand (duplex) chain.

Does it fit 10B chain?

No. 10B chain (European standard) has the same pitch and roller diameter, but a different inner width (9.65 mm instead of 9.52 mm). The ASA 50 sprocket is designed for American-standard chain, so the two systems should not be mixed.

Can a sprocket with hub be welded to the shaft?

Technically it is possible, but we do not recommend it. Welding overheats the material, can bend the shaft and damage nearby bearings, and makes later replacement of a worn sprocket very difficult. It is better to fix the sprocket with a key.

How should sprockets be aligned during installation?

The driving and driven sprockets must lie in one plane. Alignment can be checked with a long steel straightedge placed against the sides of both wheels or with a laser alignment tool. Even a small misalignment wears the sides of the teeth and speeds up chain wear.

When does a sprocket need replacing?

It should be replaced when the teeth start to look like pointed shark fins or are clearly bent to one side. Running on such a profile quickly destroys even a new chain, so a worn sprocket must be replaced.

What does the lead time depend on?

When ordering, please check the current stock level of this sprocket - the lead time depends on it and is clearly stated according to the quantity available in each warehouse. The stock level is shown above the product price and may vary depending on the warehouse.
