Shaft Installation via Key Connection
On the EAS
®
-Compact
®
with keyway, the clutch must be secured
axially after mounting onto the shaft, e.g. using a press cover
and a screw, screwed into the shaft threaded centre hole (EAS
®
-
side) and/or a set screw (adjusting screw, lastic-side, see Figs.
5, 6, 9 and 11).

Type 494._ _4._ Size 4
(Figs. 3 to 5)
The flexible elastomeric element (20) is pre-tensioned between
the metal claws by joining components 21/23/26 with component
19. For this, an axial installation force is required.
The amount of force required can be reduced by lightly greasing
the elastomeric element.
Use PU-compatible lubricants (e.g.
Mobilgrease HP 222)!
Do not place unpermittedly high axial pressure
onto the elastomeric element (20) in fully
installed state.
Please observe the distance dimension
"E" = 35 mm, see Fig. 3!

Type 494._ _4.2 Size 5
(Figs. 6 and 7)
The flexible intermediate ring (31) is pre-tensioned between the
metal claws by joining component 32 with component 19. For
this, an axial installation force is required.
The amount of force required can be reduced by lightly greasing
the intermediate ring (31).
Use PU-compatible lubricants (e.g.
Mobilgrease HP 222)!
Do not place unpermittedly high axial pressure
onto the intermediate ring (31) in fully installed
state.
Please observe the distance dimension
"Z" = 4 mm, see Fig. 6!

Type 496._ _4.2
(Figs. 8 and 9)
Join the misalignment-flexible part and the overload clutch and
screw them together using cap screws (Item 18) to the tightening
torque stated in Table 8.
Screw securement, e.g. Loctite 243, must be provided for
the cap screws (Item 18).
The clutch or the clutch hub carries out an axial
movement in the direction of the cone bushing
(13) when tightening the cone bushing (Item
13, Fig. 8).
Due to this effect, for the EAS
®
-Compact
®
clutch with disk pack (Type 496._ _4.2) please
observe that the cone bushing (13) must be
completely tightened first and then the other
(disk pack) side.
