Sprocket 08B-3 z=95 with hub, Cast iron

Product Description

Sprocket 08B-3 z=95, with cast iron hub

Sprocket 08B-3 (pitch 1/2" - 12.7 mm), triplex (three-strand), 95 teeth, with hub. The material is grey cast iron - an economical solution with good vibration damping that proves itself in drives running at constant speed; the hub has a pilot bore that must be bored out individually to suit the shaft.

Technical data

Frequently asked questions

How can you recognise a sprocket not made in accordance with the DIN 8187 profile?

Most often it is visible from the incorrect seating of the chain on the teeth - the chain "sits" on the tooth tips or too deep in the tooth roots, despite the correct pitch. In that case, it is worth placing a section of a known reference chain of this pitch on the sprocket and checking whether it engages each tooth evenly and smoothly.

Can I replace a simplex sprocket with a duplex one without changing the other drive components?

No - switching to a duplex chain and sprocket requires replacing the entire set (the sprockets on both sides of the drive and the chain) with a duplex version of the same pitch, because the rim spacing and chain width differ from those of the simplex version.

What is the relationship between the number of teeth of a sprocket and the rotational speed of the drive?

This is the basic principle of the transmission ratio. If there is a small sprocket on the motor (drive) and a large one on the machine, the machine will turn more slowly but gain proportionally greater torque (force).

In what cases are multi-strand sprockets used?

They are used to drive multi-strand chains in heavily loaded machines where there is no room for a wider sprocket with a larger pitch. Several strands distribute the load evenly, preventing premature chain breakage.

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?

This type of sprocket is used in drives of agricultural and industrial machinery, including screw and bucket conveyors, feed conveyors, packaging machines and internal transport systems.
