Plate pack screw connection
Features of plate pack screw connection
Up to bolt size M22, the plate pack screw connection on ARPEX
couplings is in the form of a close-fitting bolt connection. After
that the patented
1)
conical screw connection is used. The deci-
sive advantage of this screw connection is considerably simpli-
fied fitting. The use of an hydraulic fitting tool is no longer neces-
sary. All sizes can be fitted with a torque wrench.
A further feature of the conical screw connection is the genuine
positive connection resulting in high centering accuracy and,
thus, a high balancing quality. Material: High-grade quenched
and tempered steel.
The conical screw connection is used for the following coupling
sizes:
ARS-6 series:
size 305-6 to 602-6
ARC-8/-10 series: all sizes
ARP-6 series:
type NAN, size 325-6;
type MCECM, size 310 and 345-6
ARW-4/-6 series:
size 324-4 to 880-6
