Up to 70 teeth with hub one side, from 80 teeth supplied as disc form. The spur gears have a centre bore or pilot hole (this can vary due to manufacturing methods). For this reason, the dimension D2 max. given in the table is the maximum diameter of the bore with which the spur gears are supplied. This pilot/centre bore can be amended by the customer to produce a reamed bore, reamed bore with keyway or a tapped hole. Alternatively, customers can also use bushes to reduce the bore diameter.
