Sprocket 08B-3 z=35 with hub

Product Description

Sprocket 08B-3 z=35, with hub

Triplex (three-strand) sprocket 08B-3 with hub, 35 teeth - designed for chain with a pitch of 1/2" (12.7 mm). 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

Why are cast sprockets less precise than turned and milled ones?

Cheap castings have a rough tooth surface, hidden air bubbles and slight deformations. CNC-turned and milled sprockets mean a smooth working surface, perfect alignment and safety for the most expensive machines.

Can the hub of a sprocket have a different hardness from the toothed rim?

Yes, and in practice this is usually the case - in the version with induction-hardened teeth, only the toothed rim is hardened, while the hub remains soft so that it can be freely turned and a keyway can be cut in it. This solution combines tooth wear resistance with ease of machining the hub.

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.

How do you cut a keyway in the hub of a sprocket?

We cut keyways precisely on slotting machines according to DIN 6885. If you do it yourself, maintain axial alignment and the correct width and depth of the keyway so that the key sits securely and is not sheared off.

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.
