Sprocket 16B-1 z=12 with hub

Product Description

Sprocket 16B-1 z=12, with hub

Sprocket 16B-1 (pitch 1" - 25.4 mm), simplex, 12 teeth, with hub. 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

Do I need to select dedicated bearings for a sprocket with hub?

A sprocket with hub mounted with a key does not require its own bearings - the load is carried by the bearings of the shaft on which the sprocket is mounted. A dedicated bearing built into the sprocket is only needed for tensioning or guide sprockets mounted on an axle without its own drive.

How important is the concentricity of the hub bore relative to the toothed rim?

If the hub bore is not machined concentrically with the toothed rim, the sprocket will "run out" during operation - the teeth will engage the chain at a varying angle, which accelerates their wear and generates additional vibration. That is why boring out the pilot bore must be done on a lathe, clamping the sprocket by the hub or rim, and not "by eye".

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.

Can a sprocket with a technological bore be installed without additional machining?

No - the technological bore is deliberately too small to fit a typical shaft. It must be bored on a lathe to the required diameter and, if necessary, a keyway cut according to the requirements of the specific machine.

Where is this product used?

16B-1 sprockets operate in drives of construction machinery, goods lifts, aggregate conveyors and woodworking machines - wherever tooth durability under load matters.
