Sprocket 16B-1 z=38 with hub, Cast iron

Product Description

Sprocket 16B-1 z=38, with cast iron hub

Sprocket 16B-1, simplex, with 38 teeth and a hub - pitch 1" (25.4 mm). 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

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).

How can you check that the sprocket meshes correctly with the chain when the machine is started for the first time?

At low speed (e.g. turning the shaft by hand), it is worth observing whether the chain enters and leaves the teeth smoothly around the entire circumference of the sprocket, without catching or jumping. Any irregularities in operation at this stage usually indicate an alignment error rather than a defect in the sprocket itself.

How do you select the number of teeth on the driving and driven sprockets to obtain the required ratio?

The ratio is calculated as the quotient of the number of teeth on the driven sprocket and the number of teeth on the driving sprocket. For example, to halve the rotational speed, the driven sprocket should have twice as many teeth as the driving sprocket - both sprockets must have the same pitch and number of strands.

How does a sprocket with hardened teeth differ from the standard version (non-hardened)?

The hardened version has teeth induction-hardened to 45-55 HRC, which extends service life in drives operating continuously and under heavy load. The standard version (non-hardened) is cheaper and fully adequate for applications with moderate load or intermittent operation - our catalogue offers both variants for most pitches and numbers of teeth.

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?

16B-1 sprockets operate in drives of construction machinery, goods lifts, aggregate conveyors and woodworking machines - wherever tooth durability under load matters.
