Installation note:
For optimal performance, align cylinder axis within ±1° of load path.
Use flexible couplings for stroke lengths >500mm. Maintain 50mm minimum
clearance behind rod end for cushion adjustment. Lubricate through air
supply (ISO VG32 equivalent) if operating in high-cycle (>5Hz) conditions.
