General:
On clamping hubs (36/36.1), the clamping screw (33) is lightly
greased manufacturer-side in the thread area.
If the grease layer is washed off, the customer must re-grease
the appropriate parts. For greasing, please use NLGI Class 2
grease with a basic oil viscosity of 220 mm
2
/s at 40 °C,
e.g. Mobilgrease XHP222.
After joining both coupling halves, please test
and keep to distance dimensions "U

" or "S"

Clamping (ring) hub design
Type 486._35.0:

On clamping (ring) hubs, the torque is transmitted via
frictional locking, which means that the hub bores and
shafts must be completely grease-free during installation.
Greasy or oily bores or shafts do not transmit the
maximum clutch torque.

The shafts must not have a keyway.

The clamping hubs (32/36) must be completely relaxed
before installation; if necessary the screws (33) must be
loosened by several thread turns.

Mount the first clutch hub of the entire clutch onto the
respective shaft and bring it into the correct position.

Tighten the clamping screw(s) of the first clutch hub using
a torque wrench to the torque stated in Table 1.

Mount the second clutch hub of the entire clutch onto the
respective shaft and bring it into the correct position.

Tighten the clamping screw(s) of the second clutch hub
using a torque wrench to the torque stated in Table 1.

key design Type 486._25.0:

Mount the ROBA
®
-DS-side clutch hub (34/36.1) of the
entire clutch onto the respective shaft and bring it into the
correct position.

Tighten the clamping screw (33) or the radial set screw
(35) of this first clutch hub using a torque wrench to the
torque stated in Table 1.

Mount the second EAS
®
-side clutch hub of the entire clutch
onto the respective shaft.
3.3 EAS

®
Clamping (ring) hub design
with keyway Type 486._45.0:

The clamping hubs (32.1/36.1) must be completely relaxed
before installation; if necessary the screws (33) must be
loosened by several thread turns.

Degrease or remove preservation layers on the shafts and
bores before installing the clutch.

Mount the first clutch hub of the entire clutch onto the
respective shaft and bring it into the correct position.

Tighten the clamping screw(s) of the first clutch hub using
a torque wrench to the torque stated in Table 1.

Mount the second clutch hub of the entire clutch onto the
respective shaft and bring it into the correct position.

Tighten the clamping screw(s) of the second clutch hub
using a torque wrench to the torque stated in Table 1.
