Product Description
Sprocket 12B-1 z=30, with hub
Sprocket 12B-1 with hub, 30 teeth, simplex - a product matched to chain with a pitch of 19.05 mm (3/4"). The material is C45E carbon steel (EN 10083-1), and the teeth remain unhardened (without induction hardening) - in accordance with DIN 8187 / ISO 606; this version is easier to machine over the entire depth of the sprocket.

Frequently asked questions
What should be considered when selecting a sprocket for low-temperature operation?
At low temperatures, carbon steel becomes more susceptible to brittle fracture under impact, so in cold stores and freezers it is worth considering a variant with increased impact strength or consulting the supplier on the choice of material. Equally important is the choice of a lubricant that will not thicken or lose its lubricating properties at low temperature.
Can material documentation (certificate) for the sprocket be included with the order?
Material documentation is not sent automatically with standard catalogue orders, but if it is needed (e.g. for the machine's technical documentation), please notify the sales department when placing the order.
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.
How long can a sprocket be kept in storage without losing its properties?
A properly preserved sprocket (dried, coated with grease or anti-corrosion oil, stored in a dry room) can be kept in storage for many years without any loss of its mechanical parameters. The only risk is surface corrosion due to improper storage - it does not affect the tooth geometry, but it is advisable to clean the sprocket and preserve it again before installation.
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.
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.
