vacuum (max. 10
-7
mbar)
- humidity 10 % – 70 % (non-condensing)
- cleanroom Cleanroom class ISO 7 or ISO 6 (in accordance with ISO 14644-1)
(1)
With modified ball recirculation made of PEEK, temperatures up to +150° C (+302° F) are possible (on request). The
standard lubricant covers a temperature range from -20° C to +100° C. SCHNEEBERGER also accepts requests for
lubricants for other temperatures.
(2)
For use inhigh vacuum, the wipers on the carriages must be removed. MINIRAIL with modified ball recirculation made of
PEEK can also be operated in a vacuum (up to 10
-9
mbar) on request. Use in a vacuum requires a special lubricant available
from SCHNEEBERGER. So that no air remains trapped in the blind holes, the fastening screws must be vented.
