Sprocket 12B-1 z=24 with hub

Product Description

Sprocket 12B-1 z=24, with hub

Sprocket 12B-1 with hub, 24 teeth, simplex - a product matched to chain with a pitch of 19.05 mm (3/4"). The sprocket complies with DIN 8187 / ISO 606 and is made of C45E steel (EN 10083-1); the teeth are not hardened, which lowers the cost of the sprocket and makes it easier to machine (e.g. deep boring of the hub) throughout the entire volume of the material.

Technical data

Frequently asked questions

Is a sprocket with hub suitable for reversing drives (with a change of rotation direction)?

Yes, the tooth geometry of a sprocket is symmetrical and has no preferred direction of operation, so the sprocket can be used in drives that change direction of rotation. In such systems, correct chain tension on both sides is particularly important, because when reversing, each side alternately becomes the working side.

How can you tell whether a sprocket is still fit for further service or already due for replacement?

It is worth checking the tooth profile for visible chipping or the characteristic "hooked" shape, and also measuring the pitch circle diameter and comparing it with the catalogue dimension of a new sprocket. If the difference is visually noticeable or the chain starts to "jump", the sprocket is due for replacement.

How do you select the number of teeth on the driving and driven sprockets to obtain the required ratio?

The ratio is calculated as the quotient of the number of teeth on the driven sprocket and the number of teeth on the driving sprocket. For example, to halve the rotational speed, the driven sprocket should have twice as many teeth as the driving sprocket - both sprockets must have the same pitch and number of strands.

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.

Where is this product used?

12B-1 sprockets operate in drives of construction machinery, goods lifts, aggregate conveyors and woodworking machines - wherever tooth durability under load matters.
