Sprocket 28B-1 z=10 with hub

Product Description

Sprocket 28B-1 z=10, with hub

Sprocket 28B-1, simplex, with 10 teeth and a hub - pitch 1 3/4" (44.45 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 can you tell whether a sprocket is still fit for further service or already due for replacement?

It is worth checking the tooth profile for visible chipping or the characteristic "hooked" shape, and also measuring the pitch circle diameter and comparing it with the catalogue dimension of a new sprocket. If the difference is visually noticeable or the chain starts to "jump", the sprocket is due for replacement.

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).

How do I determine the centre distance between the driving and driven sprockets?

The centre distance should provide an adequate chain wrap angle on the smaller sprocket (usually a minimum of about 120°) and sufficient chain length so that the number of links is a whole number, preferably even. Too small a centre distance increases the meshing frequency and accelerates wear, while too large a one leads to excessive chain sag.

How do I select a sprocket for a roller chain?

The selected sprocket must match the chain parameters exactly. Pay attention to three things: the standard (European B series), the pitch and the number of strands. The sprocket must have a tooth profile compliant with DIN 8187 so that the chain enters the tooth root smoothly without jamming.

Where is this product used?

28B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
