Sprocket 08B-3 z=13 with hub

Product Description

Sprocket 08B-3 z=13, with hub

Triplex (three-strand) sprocket 08B-3 with hub, 13 teeth - designed for chain with a pitch of 1/2" (12.7 mm). The material is C45E carbon steel (EN 10083-1), and the teeth remain unhardened (without induction hardening) - in accordance with DIN 8187 / ISO 606; this version is easier to machine over the entire depth of the sprocket.

Technical data

Frequently asked questions

How do you select a sprocket when the machine lacks space for a larger pitch?

In such a situation, a better solution than increasing the pitch is often to use a multi-strand chain and sprocket of the same (smaller) pitch - several strands together carry a greater load without increasing the sprocket diameter.

Is it possible to order a single trial piece of the sprocket before placing a larger order?

Yes, catalogue items can be ordered in any quantity, including a single piece for testing or verification before a larger series order.

What does the marking "z=X" on a sprocket mean and why is it so important when ordering?

"z" is the number of teeth of the sprocket - together with the pitch and the number of chain strands, it unambiguously defines the sprocket geometry (pitch circle and outside diameter). Ordering a sprocket with the wrong "z" usually means that it will not work correctly with the second sprocket already in the machine, and a different transmission ratio than intended will result.

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.

When placing your order, please check the current stock level of this gear - the lead time depends on it and is clearly stated according to the quantity available in the given warehouse.
