Shaft Installation via Key Connection
On the EAS
®
-compact
®
with a keyway, the clutch must be axially
secured both EAS
®
-side and lastic-side after mounting onto the
shaft, e.g.:
for Type 490.
with a press cover and a screw, screwed into the shaft
threaded centre hole
for Types 494. and 496.
on the EAS
®
-side with a press cover and a screw, screwed
into the shaft threaded center hole and on the lastic-side with
a locking set screw:
locking set screw (36) for hub (32.3), see Fig. 1 on page 3
and Table 10 on page 6,
locking set screw (37) for hub (19.2), see Fig. 1 on page
3, Fig. 6 on page 11 and Table 13 on page 7.
Joining Both Clutch Components (1/32)
for Type 494._ _ _._ (Figs. 1 and 7)
The flexible elastomeric element (31) is pre-tensioned between
the metallic claws by joining the components (32.1, 32.2 or 32.3)
with the connection flange (29). To do this, an axial installation
force is required.
The force required can be reduced by lightly greasing the
elastomeric element.
Use PU-compatible lubricants (e. g. Vaseline or
a multi-purpose grease based on mineral oil,
NLGI Class 2, with a basic oil viscosity of
approx. 200 mm
2
/s).
No unpermittedly high axial pressure should be
placed on the elastomeric element (31) in
completely assembled condition.
Keep to distance dimension “E” acc. Fig. 7
and Table 10!

Joining Both Clutch Components
Type 496._ _ _._ (Fig. 1)
Join the misalignment-flexible part and the overload clutch and
screw together with cap screws (18) to the tightening torque
75 Nm.
The cap screws (18) must be protected using a screw-
securing product, e.g. Loctite 243.
