Sprocket 06B-1 (3/8") z=114 with hub, cast iron

Product Description

Sprocket 06B-1 (3/8") z=114 with hub, cast iron fits 06B-1 roller chain (European standard DIN 8187 / ISO 606), single-strand (simplex), with a pitch of 9.525 mm (3/8"). 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 Ø19 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 40 mm.

Technical data

Applications

It is found in textile machinery, gate and roller shutter drives and workshop equipment. 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 06B-1 z=114 sprocket fit?

06B-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 9.525 mm. A simplex sprocket requires a single-strand (simplex) chain.

Does it fit ASA 35 chain?

No. ASA 35 chain (American standard) has the same pitch, but a different roller diameter (5.08 mm instead of 6.35 mm) and a different inner width (4.77 mm instead of 5.72 mm). The 06B sprocket is designed for European-standard chain, so the two systems should not be mixed.

When should I choose a sprocket with hub and when a plate wheel?

A sprocket with hub is chosen when it transmits torque directly from the shaft via a key - the hub provides a longer contact surface with the shaft and a more stable fit. Plate wheels are used mainly when the wheel is fixed to an existing flange or drum, or when there is little space on the shaft.

How does the number of teeth affect the drive ratio?

The ratio is the number of teeth of the driven wheel divided by the number of teeth of the driving wheel. If this sprocket drives a wheel with twice as many teeth, the driven shaft turns twice as slowly but with roughly twice the torque.

Why does the sprocket have a pilot bore and how is it machined?

The pilot bore Ø19 mm is left on purpose so that it can be bored precisely to the machine shaft size. The sprocket is clamped in a lathe by the outer edge of the hub to avoid run-out, and the bore is usually machined to H7 tolerance. The maximum bore diameter depends on the hub diameter.

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.
