Sprocket 10B-3 z=8 with hub

Product Description

Sprocket 10B-3 z=8, with hub

The sprocket 10B-3 shown is a triplex (three-strand) sprocket with 8 teeth, made with a hub, for chain with a pitch of 5/8" / 15.88 mm. Compliance with DIN 8187 / ISO 606 guarantees full interchangeability with a chain of the same pitch; the sprocket is made of C45E steel (EN 10083-1) in a non-hardened version - the standard choice for applications with moderate and medium load.

Technical data

Frequently asked questions

How can you check whether the chain in an existing drive is already excessively elongated (stretched)?

Stretch out a section of a dozen or so chain links and compare its length with the catalogue dimension - an elongation of more than approx. 2-3% means the chain is due for replacement. A stretched chain no longer seats properly on the sprocket teeth, which accelerates the wear of both components, so it is better to replace it before it damages the sprocket as well.

Does the machine's operating temperature matter when choosing the sprocket material?

Yes - at very low or very high temperatures the mechanical properties of steel or cast iron change, and lubricants may change viscosity or thicken. Under unusual thermal conditions (cold stores, furnaces, dryers), it is advisable to consult the supplier before selecting a specific material variant.

Can a sprocket be reconditioned, e.g. by hardfacing worn teeth?

Technically, hardfacing and re-milling the teeth is possible, but in practice it is rarely cost-effective - the cost of reconditioning is often close to the price of a new sprocket, and restoring the full precision of the tooth profile requires specialist machining. In most cases, replacing it with a new sprocket is the quicker and safer solution.

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.

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.
