- CNC machine tool chip conveyors
- Automotive welding fixture positioning
- Food processing packaging actuators
Installation guidelines:
Maintain 0.5-1mm clearance between rod end and load during alignment.
For vertical mounting, use locknut (A06-402) on piston rod. Lubricate every
3,000km stroke or 6 months with AirTAC AFF-1 grease.
