- Plastic injection molding machine ejectors
- Steel mill roller adjustment mechanisms
- Automotive welding fixture positioning
- Paper processing equipment tension control
Installation guidelines:
Requires rigid mounting surface with ≤0.1mm/m flatness. For horizontal
installations over 500mm stroke, recommend using rod support brackets
(AS-MFH63). Lubricate through air supply (ISO VG32 pneumatic oil).
Avoid side load exceeding 150N.
