2. For the bolted rotor connection (see Fig. 5.9), use DIN EN ISO 4762 hexagon socket
screws of the property class stated in Table 4.1, in a suitable length (dependent on the
connection geometry, see Table 5.1 on Page 17).
We recommend DIN EN ISO 4762 fillister head screws, blackened, smooth-headed,
permitted size and shape variance in accordance with DIN ISO 4759, Part 1, product
class A.
Important
Use a screw locking device (medium strength, e.g. LOCTITE No. 242) to glue the screws
into the counter thread to exclude pre-stressing loss due to screw slackening, if alternating
loads are to be expected.
3. Fasten all screws with the specified torque
(Table 5.1 on Page 17).
4. There are tapped holes on the rotor for further mounting. Also use screws of property
class 10.9 or 12.9, and fasten with the torque specified in Table 5.1.
