1.Outline of clean room specification 11-clean specification actuator is a vacuum type. Please it is a customer, the business mind getting a clean coupling, and lay pipes. Please adjust and use the amount of the vacuum according to a clean class and use Actuator speed. 1.1 Grease used
The special grease is used for the guide and the ball screw. Please confirm it to our company when you maintain the grease up etc.
1.2 Recommended tube diameter Recommended tube diameter
Type Tube diameter(mm) 40,63 8 or more * An enough fluence is not obtained by a diameter that is thinner than this. Moreover, please enlarge it by one size when the piping length exceeds 3m.
Caution When using it excluding specified grease
When wrong grease is used, particle might be increased. According to circumstances, please note that raising dust is increased even if the low raising dust greases other than specification are used. Especially, please do not use fluorine system grease.
2.Raising dust characteristic 2.1 Recommended tube diameter The figure below shows the amount of the vacuum aspiration and the raising dust degree. (reference value)
