- Automotive welding fixture positioning
- Injection molding machine ejector systems
- Steel mill conveyor gate actuators
- Palletizing robot end-effector drives
Installation guidelines:
Align cylinder axis within ±0.5° of load path. For vertical mounting,
use mechanical locks to prevent piston drift. Lubricate with ISO VG32
hydraulic oil if operating below 0.3 MPa. Magnetic switches should be
positioned 10mm beyond cushion zones.
