Installation guidance:
Maintain 0.5mm minimum clearance between stopper nuts. Lubricate through
air supply (ISO VG32 recommended). Avoid side load exceeding 50N. Adjust
cushion screws gradually (1/4 turns) for optimal deceleration.
Requires 5μm filtered air.
Maximum side load capacity: 300N at mid-stroke. Stroke adjustment
should never exceed 110% of nominal stroke length.
