Sprocket 24B-1 z=40 with hub

Product Description

Sprocket 24B-1 z=40, with hub

Sprocket 24B-1, simplex, with 40 teeth and a hub - pitch 1 1/2" (38.1 mm). The sprocket complies with DIN 8187 / ISO 606 and is made of C45E steel (EN 10083-1); the teeth are not hardened, which lowers the cost of the sprocket and makes it easier to machine (e.g. deep boring of the hub) throughout the entire volume of the material.

Technical data

Frequently asked questions

How does a sprocket differ from a module spur gear?

A sprocket works with a roller chain and has a tooth profile matched to the chain rollers (standard DIN 8187/ISO 606), whereas a module spur gear meshes directly with another gear or a gear rack, has an involute tooth profile and parameters described by the module (standard DIN 780/ISO 54). These are two different power transmission systems, not interchangeable with each other.

When ordering several sprockets for one drive, do they have identical production parameters?

Sprockets of the same catalogue item are produced according to the same documentation and tolerances, so their parameters (pitch, number of teeth, dimensions) match each other regardless of when they were ordered. Any slight differences in the shade of the steel between production batches have no effect on how the sprocket works with the chain.

What is the standard procedure for submitting a complaint about a sprocket?

It is advisable to contact customer service, providing the product code, order number, and a description and photos of the observed defect - this makes it possible to quickly assess whether the complaint is justified and to propose further steps.

How does the choice of the number of teeth affect vibration levels and drive operation?

A smaller number of teeth means fewer meshing points per revolution and larger fluctuations in the instantaneous chain speed (the so-called polygon effect), which results in higher vibration levels. Increasing the number of teeth of the sprocket (at the same pitch) smooths the operation of the drive, although it increases its overall dimensions.

Where is this product used?

24B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
