Sprocket 10B-1 z=21 with hub

Product Description

Sprocket 10B-1 z=21, with hub

Simplex sprocket 10B-1 with hub, 21 teeth - designed for chain with a pitch of 5/8" (15.88 mm). As a European manufacturer, Ozdowski supplies the sprocket in C45E steel (EN 10083-1), in accordance with DIN 8187 / ISO 606 - a version without tooth hardening, cheaper than the hardened variant and sufficient for many typical industrial applications.

Technical data

Frequently asked questions

How do you select a sprocket when the machine lacks space for a larger pitch?

In such a situation, a better solution than increasing the pitch is often to use a multi-strand chain and sprocket of the same (smaller) pitch - several strands together carry a greater load without increasing the sprocket diameter.

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.

Does the difference in hardness between sprocket and chain affect their rate of wear?

Yes - chain and sprocket manufacturers select hardness so that they wear as evenly as possible, rather than one element "cutting down" the other. An excessively hard sprocket working with a soft, non-certified chain (or vice versa) leads to faster wear of the weaker element.

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.

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.
