Sprocket 08B-3 z=25 with hub

Product Description

Sprocket 08B-3 z=25, with hub

Triplex (three-strand) sprocket 08B-3 with hub, 25 teeth - designed for chain with a pitch of 1/2" (12.7 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

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.

How does material quality prevent the teeth from "shearing" during sudden machine jerks?

Soft, uncertified sheet metal deforms under a sudden jerk - the teeth bend over. Steel from a certified melt, correctly heat-treated, has a high yield strength and withstands a torque surge without permanent deformation.

Can a sprocket be welded directly to the drive shaft?

Technically this is possible, but we strongly advise against such a solution. Welding overheats the material, damages nearby bearings, bends the shaft and prevents the worn sprocket from being easily replaced later. Always use mounting with a key or a clamping bush.

Does a sprocket with hub have a fixed mounting side, or can it be reversed?

The sprocket is usually symmetrical with respect to the plane of the rim, so the rim itself cannot be "reversed incorrectly" - but the hub is usually on only one side of the sprocket, which determines which way the sprocket must be mounted relative to other components on the shaft (e.g. bearings, other sprockets).

Where is this product used?

Typical applications of the 08B-3 sprocket: drives for pumps, mixers and industrial fans, as well as control systems for industrial gates and roller shutters, where resistance to continuous operation is required.
