Product Description

Sprocket 10B-1 z=42, hardened hub

Sprocket 10B-1 with hardened hub, 42 teeth, simplex - a product matched to chain with a pitch of 15.875 mm (5/8"). Made in accordance with DIN 8187 / ISO 606, from C45E steel (EN 10083-1), with teeth induction hardened to 45-55 HRC - as a Polish manufacturer, Ozdowski ensures that the hub remains soft and suitable for turning.

Technical data

Frequently asked questions

How do I bore the hole in a sprocket to fit a motor shaft?

A sprocket with a pilot bore should be clamped in a lathe (gripping the hub to avoid runout) and bored to the required diameter with an H7 tolerance. If the sprocket has hardened teeth, the hub is usually soft and easy to machine.

Can a new chain be fitted on an old, worn sprocket?

Never do this. An old, deformed sprocket has altered tooth geometry and will force drastic mechanical stretching on the new chain. The rule is "new chain - new sprocket" - only then will the drive achieve maximum service life.

What is a technological bore in a sprocket and why is it left?

We manufacture sprockets with hub with a small, so-called pilot (preliminary) bore. We leave it deliberately so that the customer (or workshop) can bore it precisely to the exact shaft size of their machine.

When should I choose a sprocket with hub and when a flat one (plate wheel)?

Flat sprockets (plate wheels) are most often used where they are mounted onto an existing flange or drum, or when there is extremely little space on the shaft. We choose a sprocket with hub when it must reliably transmit high torque directly from the shaft via a key - the hub provides a longer contact surface.

Where is this product used?

This type of sprocket is used in drives of agricultural and industrial machinery, including screw and bucket conveyors, feed conveyors, packaging machines and internal transport systems.
