Description

Material
Low-carbon steel.
Version
Bright, not hardened (cannot be hardened).
Note
Sprockets for DIN ISO 606 roller chains.
The disc sprockets have a centre bore or are pre-drilled (this can vary due to production methods). For this reason, the dimension D3 max. given in the table is the maximum diameter of the bore that the disc sprockets are supplied with. This pilot hole/centre bore can be customised with a reamed hole, reamed hole with keyway or a tapped hole by the customer. Alternatively, bushes can be fitted by the customer to reduce the diameter.
