- Material handling systems with adjustable clamping force
- Packaging machine stopper adjustment mechanisms
- Plastic injection molding ejector systems
- Semiconductor wafer handling equipment
Operation guidance:
Always loosen both locknuts before stroke adjustment. Use 32mm spanner for stopper rotation.
Recommended lubrication: ISO VG32 turbine oil. Avoid exceeding 0.7 MPa during position calibration.
Critical note:
Maintain minimum 0.3mm concentricity between piston rod and load connection.
For vertical installations, use SEJ100X125-75S/V variant with reinforced rod end bearing.
