Sprocket 08B-3 z=10 with hub

Product Description

Sprocket 08B-3 z=10, with hub

Sprocket 08B-3 (pitch 1/2" - 12.7 mm), triplex (three-strand), 10 teeth, with hub. Compliance with DIN 8187 / ISO 606 guarantees full interchangeability with a chain of the same pitch; the sprocket is made of C45E steel (EN 10083-1) in a non-hardened version - the standard choice for applications with moderate and medium load.

Technical data

Frequently asked questions

How can you recognise an idler sprocket bearing that is starting to wear before it fails?

The first symptom is usually increased noise and noticeable, excessive play of the sprocket when it is moved by hand with the machine stopped. It is also worth periodically checking the temperature of the bearing housing during operation - an increase compared with other bearings in the system signals progressive wear.

Will a sprocket from another manufacturer work properly with the chain I already have?

If the sprocket is made to the same standard (DIN 8187/ISO 606) and has the same pitch and number of strands, it should work properly with a chain of another brand - that is the purpose of standardisation in this industry. However, differences between manufacturers may concern, for example, hub dimensions or material, so these parameters are worth checking separately.

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.

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.

Where is this product used?

08B-3 sprockets operate in drives of construction machinery, goods lifts, aggregate conveyors and woodworking machines - wherever tooth durability under load matters.
