A heavy-duty industrial cylinder featuring precision honed tubing and triple lip seals for leak-free operation. The SI80X280SFB combines high moment resistance (up to 68 N·m) with smooth stroke completion via tunable air cushions. Its corrosion-resistant construction supports operation in humid environments when paired with proper air treatment.
- Automotive press line material handling systems
- Plastic injection molding machine ejectors
- Steel coil lifting/press fixtures
- Packaging line palletizing arms
- Paper mill roller positioning mechanisms
Installation notes:
- Align within 0.2mm/m perpendicularity tolerance during mounting
- Use flexible couplings for lateral force absorption
- Lubricate via air line lubricator (ISO VG32 recommended)
- Allow 50mm clearance behind rod end for maintenance
