Installation note:
Use locknuts (M16) with 24-28 N·m torque for rod end connections.
For stroke adjustment: Loosen locknut, rotate adjustment screw (1 full rotation = 1.5mm stroke change),
then retighten while maintaining piston position. Lubricate with ISO VG32 hydraulic oil.
Maximum side load: 150N. For vertical installations exceeding 45° angle,
use guided cylinder configuration. Maintain 0.3 MPa minimum pressure for stable cushioning performance.
