Sprocket 06B-1 z=95 with hub, Cast iron

Product Description

Sprocket 06B-1 z=95, with cast iron hub

Sprocket 06B-1 (pitch 3/8" - 9.53 mm), simplex, 95 teeth, with hub. 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.

Technical data

Frequently asked questions

How do you cut a keyway in the hub of a sprocket?

We cut keyways precisely on slotting machines according to DIN 6885. If you do it yourself, maintain axial alignment and the correct width and depth of the keyway so that the key sits securely and is not sheared off.

How should large-diameter sprockets be transported and stored to prevent deformation?

Large sprockets are best stored and transported lying flat on a level, stable surface, rather than resting on the toothed rim alone, which is more susceptible to local deformation. When lifting, it is advisable to use slings passed through the hub bore rather than hooking them onto individual teeth.

How important is the concentricity of the hub bore relative to the toothed rim?

If the hub bore is not machined concentrically with the toothed rim, the sprocket will "run out" during operation - the teeth will engage the chain at a varying angle, which accelerates their wear and generates additional vibration. That is why boring out the pilot bore must be done on a lathe, clamping the sprocket by the hub or rim, and not "by eye".

How do I determine the centre distance between the driving and driven sprockets?

The centre distance should provide an adequate chain wrap angle on the smaller sprocket (usually a minimum of about 120°) and sufficient chain length so that the number of links is a whole number, preferably even. Too small a centre distance increases the meshing frequency and accelerates wear, while too large a one leads to excessive chain sag.

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?

06B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
