High-force industrial cylinder with oversized piston diameter for heavy load applications. Features triple sealing system (rod seal, buffer seal, and piston seal) with integrated magnetic field for position sensing. Anti-rotation design maintains payload orientation during long strokes. Compatible with ISO mounting accessories (front flange, foot, and rear pivot).
- Automotive press line material handling
- Steel coil lifting and positioning systems
- Injection molding machine ejectors
- Shipbuilding fixture clamping mechanisms
- Construction equipment actuators
Installation notes:
Use M12x1.75 mounting bolts (grade 8.8 or higher).
Maintain 0.5mm minimum alignment tolerance between rod and load.
Requires 20-50μm filtered air with ISO VG32 lubrication.
First stroke should be performed at 0.3MPa for seal conditioning.
