| Areas of application | |
| - temperature range (1) | -40 °C to +80 °C (-40 °F to +176 °F) |
| - vacuum (2) | vacuum (max. 10-7 mbar) |

(1) Depending on the load, temperatures of up to +150 °C (+302 °F) are possible with modified ball recirculation made of PEEK (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.
