- Plastic injection molding machine ejectors
- Automotive assembly line positioning
- Packaging machine actuation systems
- Press brake tooling adjustment
Installation note:
For optimal performance in vertical installations, use auxiliary rod support when stroke exceeds 500mm.
Maintain 0.3mm minimum alignment tolerance during mounting. Lubricate through air supply (ISO VG32 recommended)
if using non-lubricated version.
