Installation guidelines:
Maintain 0.05-0.1mm clearance between cylinder body and mounting surface.
Apply ISO VG32 hydraulic oil for initial lubrication. Avoid side load exceeding 30N.
Recommend using AIRTAC MAL-6 locking module for position retention.
Maintenance alert:
Replace buffer seals every 500,000 cycles in high-frequency applications.
Always depressurize before adjusting locking positions.
Use 5-40μm filtered compressed air with ISO 8573-1:2010 Class 3.4.2 air quality.
