Heavy-duty industrial cylinder featuring large bore design for high thrust requirements. The LB variant includes built-in magnet for position sensing compatibility with magnetic switches (D-A93 series). Enhanced buffer design reduces end-impact noise to <75dB(A) at 0.5MPa. Optional corrosion-resistant versions available for marine environments.
- Press machine clamping mechanisms
- Automated foundry equipment actuators
- Plastic injection molding ejectors
- Heavy conveyor gate controls
- Paper processing machinery
Installation guidelines:
- Allow 10mm clearance around cylinder body for heat dissipation
- Use M6 mounting screws (grade 8.8 or higher)
- Align piston rod within 0.2mm perpendicular tolerance
- For vertical mounting, specify "V" orientation code
