Installation tip:
For vertical mounting applications exceeding 45° angle, install an external guide mechanism to prevent piston rod side-load. Relubricate every 5 million cycles using ISO VG32 hydraulic oil.
Critical note:
Avoid using silicone-based lubricants which may degrade NBR seals. Maximum lateral load capacity: 150N at full extension.
