Sprocket 08B-1 (1/2") z=114 with hub, cast iron

Product Description

Sprocket 08B-1 (1/2") z=114 with hub, cast iron fits 08B-1 roller chain (European standard DIN 8187 / ISO 606), single-strand (simplex), with a pitch of 12.7 mm (1/2"). It has 114 teeth and is made of EN-GJL-250 cast iron.

The sprocket has a one-sided hub with a diameter of 80 mm and a pilot bore of Ø23 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 suits go-karts, recreational vehicles and small garden machinery. The cast iron design works well for large sprockets in reduction gears, where rigidity and vibration damping matter.

Frequently asked questions

Which chain does the 08B-1 z=114 sprocket fit?

08B-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 12.7 mm. A simplex sprocket requires a single-strand (simplex) chain.

Does it fit ASA 40 chain?

No. ASA 40 chain (American standard) has the same pitch, but a different roller diameter (7.94 mm instead of 8.51 mm) and a different inner width (7.94 mm instead of 7.75 mm). The 08B sprocket is designed for European-standard chain, so the two systems should not be mixed.

How is a keyway cut in the hub?

The keyway is made to DIN 6885, keeping it aligned and with the correct width and depth so that the key sits firmly. The key should fit accurately - play in the keyway accelerates wear and, under shock loads, can lead to the key shearing off.

What is the set screw hole in the hub for?

The threaded hole, usually made above the keyway or at 90° to it, takes a headless set screw. It prevents the sprocket from sliding along the shaft when the machine vibrates.

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.

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.
