The SEJ50X160-75S features precision stroke adjustment through its unique mechanical locking mechanism, allowing ±0.5mm repeat positioning accuracy. Its double-acting design with corrosion-resistant construction enables operation in humid environments. The auto-switch groove (T-slot) accommodates multiple sensor types for position feedback.
- Variable height positioning in packaging line conveyors
- Pressure-sensitive clamping in CNC fixture systems
- Adjustable stopper mechanisms in automotive assembly
- Precision web tension control in printing machinery
- Modular robotic end effector positioning
Installation Guidelines:
Use locknuts (not included) with 28-32 N·m torque for stroke adjustment mechanism.
Lubricate with ISO VG32 hydraulic oil if operating below 0.3 MPa. Maintain 0.3mm minimum
parallel alignment tolerance during mounting.
