Description

Material
Steel 1.0503 (C45).
Version
Milled toothing, straight teeth.
Engagement angle 20°, bright.
Note
The spur gears have a center bore or are pre-drilled (this may vary depending on the manufacturing process). For this reason, the dimension D2 max. given in the table is the maximum diameter of the bore that the spur gears are supplied with. This pilot hole/center bore can be customized with a reamed hole, reamed hole with keyway or a tapped hole by the customer.
In order to achieve exact concentricity between the toothing and the bore, we recommend enlarging the pilot hole to the required diameter on a lathe. Alternatively, bushings can be fitted by the customer to reduce the diameter.
