Note
The lubrication intervals S
int
depend on the actual stress on the EGC.
S
Shorten the lubrication intervals S
int
(
Fig.19) to half the length in case of:
Dusty and dirty environments
Nominal strokes>2000mm
Travel profile
Z
triangular operation (frequent acceleration and braking)
Ambient temperatures>40°C
EGC which has been in operation>3years.
We recommend that you lubricate the recirculating ball bearing guide and
the bearing guide at the same time. The shorter lubrication interval applies
in this case.

:
1. Calculate the spindle comparison number

3. Move the along the entire path of travel
whilst greasing so that the grease is distri
buted evenly.
