Installation guidelines:
Maintain 0.5-1 mm alignment tolerance during mounting. Use flexible couplings when lateral forces exceed 10% of rated thrust.
For vertical mounting, install with piston rod facing downward to prevent debris accumulation. Lubricate every 5 million cycles
using ISO VG32 hydraulic oil in lubricated systems.
- Filtered air (5-40 micron)
- Dew point -25℃ below ambient temperature
- Oil content 0.1-1 mg/m³ (when using non-lubricated air)
