Product Description

Sprocket 28B-3 z=13, with hub

Sprocket 28B-3 with hub, 13 teeth, triplex (three-strand) - a product matched to chain with a pitch of 44.45 mm (1 3/4"). Manufactured in accordance with DIN 8187 / ISO 606 from C45E structural steel (EN 10083-1), without tooth hardening - as a Polish manufacturer, Ozdowski supplies an economical version that is fully dimensionally interchangeable with the hardened variant of the same pitch.

Technical data

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 often should chain tension be checked on a machine in operation?

In machines operating continuously, it is advisable to check the tension every few weeks, and in a newly installed drive - as early as after the first hours of operation, when the chain "beds in". A correctly tensioned chain has a slight, visible sag on the slack side - too tight a chain accelerates bearing wear, while too loose a chain increases the risk of it jumping off the sprocket.

How do I check the radial and axial runout of a sprocket after mounting it on the shaft?

A dial indicator on a magnetic stand is used for the measurement. Place the tip against the circumference of the sprocket or its side face, rotate the shaft and check the deviations. Excessive runout indicates faulty installation or a damaged shaft.

Where is this product used?

28B-3 sprockets operate in drives of construction machinery, goods lifts, aggregate conveyors and woodworking machines - wherever tooth durability under load matters.
