All specifications assume the PRT is assembled with socket head screws (strength class 8.8) on the outside pitch circle diameter of the head ring. The slewing ring bearings are mounted using screws (strength class 8.8) with a minimum thread depth of 2 x d for every hole in the outer ring.
 
PRT-01-20: M4, min. 6 screws PRT-01-30: M4, min. 8 screws PRT-01-60: M5, min. 10 screws PRT-01-100: M5, min. 12 screws PRT-01-200: M6, min. 12 screws
 
All data can be used for both lateral and horizontal assembly (including overhead installation).

 

Handling and conveyance system for semiconductor transport/box.

 

The complete system is suitable for clean rooms, free of lubrication and maintenance.
