Sprocket 12B-1 z=35 with hub, hardened

Product Description

Sprocket 12B-1 z=35, hardened hub

Sprocket 12B-1 (pitch 3/4" - 19.05 mm), simplex, 35 teeth, with hardened hub. As a European manufacturer, Ozdowski supplies the sprocket in C45E steel (EN 10083-1), in accordance with DIN 8187 / ISO 606 - the teeth are induction hardened (45-55 HRC), while the hub remains soft and easy to machine.

Technical data

Frequently asked questions

What does the pitch of a sprocket mean and how can it be checked?

The pitch of a sprocket corresponds to the chain pitch - it is the theoretical distance between the centres of adjacent teeth on the pitch circle. The easiest way to check it is to place a section of matching chain on the sprocket - it should sit perfectly, without tension.

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.

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.

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?

Applications include drives in the food industry, packaging machines, sorting lines and agricultural harvesting machines, where the sprocket operates seasonally but under full load.
