6.1.5
Balancing
FLUDEX couplings with prebored hubcarrier part (120) are delivered balanced. The fluid coupling is G 6.3
balanced in two levels with fluid filled in (halfkey balancing). If the addon coupling has been fitted with
finished bores, it is G 6.3 balanced in two levels (halfkey balancing).
Prebored addon coupling parts are delivered unbalanced. It is recommended that these parts are
balanced to suit the application after finishboring (see standards "DIN ISO 1940" and "DIN 740/2");
minimum balancing quality G16.
Balancing is normally done by drilling material away.
If onelevel balancing is required on brake disk or brake drum (32), the material on the front end at the disk's
bottom is to be removed. When twolevel balancing the brake drum (32) or the brake disk (32) and part 11
should be balanced together with part 10, and part 11 of the "FNDBHB" together with part 10 and the
brake disk (8).
WARNING
Risk of serious injury through flying fragments
Risk of serious injury through flying fragments and/or incorrect bore position and bore design.
Balancing bores must not affect the loadbearing capacity of the coupling parts.
In case of coupling part 1 the bottom of the pockets of the flexible elements must not be completely drilled
through.
On part 32 the brake surface must not under any circumstances be damaged.
Finishbored couplings and/or coupling parts are balanced according to the customer's specifications.
