Sprocket 08B-1 z=13 with hub, hardened

Product Description

Sprocket 08B-1 z=13, hardened hub

Sprocket 08B-1 (pitch 1/2" - 12.7 mm), simplex, 13 teeth, with hardened hub. Sprocket compliant with DIN 8187 / ISO 606, milled from C45E steel (EN 10083-1); the teeth are induction hardened (45-55 HRC), while the core and hub remain soft, allowing the bore to be safely machined to the shaft size.

Technical data

Frequently asked questions

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 does a hardness of around 45-55 HRC on the teeth extend the service life of the sprocket-chain system?

A hardness of 45-55 HRC matched to the hardened chain rollers is the optimal combination. The sprocket and chain wear slowly and evenly, and the sprocket does not turn into a "blade" that could shear the chain during operation.

How do I check the radial and axial runout of a sprocket after mounting it on the shaft?

A dial indicator on a magnetic stand is used for the measurement. Place the tip against the circumference of the sprocket or its side face, rotate the shaft and check the deviations. Excessive runout indicates faulty installation or a damaged shaft.

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.

Where is this product used?

08B-1 sprockets operate in the drives of construction machinery, goods lifts, aggregate conveyors and woodworking machines - wherever tooth durability under heavy load matters.
