- Automotive assembly line clamping units
- Injection molding machine core pullers
- Bulk material handling gates
- Paper mill roller positioning
Installation note:
Ensure parallel alignment of mounting surfaces (max 0.1mm/m deviation).
For vertical installations, use rod-down orientation with 10% oversize
cushioning adjustment. Lubricate through air supply at 1-2 drops/m³.
