Sprocket 06B-3 z=38 with hub, Cast iron

Product Description

Sprocket 06B-3 z=38, with cast iron hub

The sprocket 06B-3 shown is a triplex (three-strand) sprocket with 38 teeth, made with a hub, for chain with a pitch of 3/8" / 9.53 mm. The sprocket is made of grey cast iron - a traditional material for sprockets in applications with moderate loads and lower rotational speeds; the bore in the hub is a pilot bore intended to be machined to the shaft size.

Frequently asked questions

If I order today, when will I receive the product?

Information on the lead time is given next to the product's stock level, above the price. If the sprocket is available in the main warehouse, we ship it no later than the next working day.

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.

What does the marking "z=X" on a sprocket mean and why is it so important when ordering?

"z" is the number of teeth of the sprocket - together with the pitch and the number of chain strands, it unambiguously defines the sprocket geometry (pitch circle and outside diameter). Ordering a sprocket with the wrong "z" usually means that it will not work correctly with the second sprocket already in the machine, and a different transmission ratio than intended will result.

When is it worth using a clamping bush (Taper Bush) for a sprocket?

Wherever fast assembly matters. A clamping bush eliminates the need for laborious boring of the hub and cutting of a keyway - you insert the sprocket, tighten the screws and the machine is back in operation within minutes.

Does a cast iron sprocket require a different chain than a steel sprocket of the same pitch?

No - the tooth geometry and pitch are identical to those of the steel version of the same size, so the cast iron sprocket works with the same chain. The difference lies in the material of the hub and rim: cast iron dampens vibrations better and is cheaper, but withstands impacts and operation at high rotational speeds less well than steel.

Where is this product used?

Applications include drives in the food industry, packaging machines, sorting lines and agricultural harvesting machines, where the sprocket operates seasonally but under full load.

When placing your order, please check the current stock level of this gear - the lead time depends on it and is clearly stated according to the quantity available in the given warehouse.
