Ele ctric cylin der s S RS A , SVS A a n d S L S A
NOTE
To check the cylinder temperature, there is a temperature sensor
option that can be ordered when cylinder is ordered or added
afterwards if the cylinder is returned to Ewellix.
For more information on this option, please contact your local
Ewellix representative.
NOTE
During re-lubrication actions, please take the following
indications into account:
• Work cleanly. Do not inject grease polluted by other products or
particles.
• Too much grease generates heat inside the actuator.
• Avoid injecting air into lubrication paths.
5.2.1 Roller screw (or ball screw)
Type:
See user manual (specific data)
Quantity:
See user manual (specific data)
Period:
See user manual (specific data)
Procedure:
1 Position the cylinder at the greasing po-
sition (see user manual (specific data)).
2 Inject half the required amount of
grease.
3 Make ten double strokes slowly along
the whole stroke to spread the grease
along the screw shaft.
4 Repeat steps 1, 2 and 3.
This is a closed system. Re-lubrication is most effective if
the old grease is removed. The state of the old grease can
be seen and the quantity and period of re-lubrication modi-
fied to suit the real operating conditions (temperature,
speed, load, etc). While re-lubricating, the old grease goes
into free space in the cylinder. If all free space is filled, the
cylinder would overheat.
Please contact your local Ewellix representative for advice
on services that Ewellix offers for cylinder maintenance.
5.2.2 Bearings
The bearings are greased for life.

If this option has been taken, re-lubrication data is as
follows:
Type:
See user manual (specific data)

Until it overflows
Period:
See user manual (specific data)
Procedure:
1 Position the cylinder in the middle of its
stroke.
2 Remove the two plastic covers if nec-
essary (⮑ fig. 1 or 3).
3 Inject grease into the hole (⮑ fig. 2), or
the nipple (⮑ fig. 4, page 29) of every
