- Glass tempering oven door actuators
- Automated pallet height adjustment systems
- Textile machinery tension control units
- Automotive welding fixture positioning
Installation best practice:
Always align cylinder axis within ±0.2° angular misalignment. For horizontal mounting,
use rod support brackets when stroke exceeds 150mm. Pre-lubricate with AirTAC P-1
grease before initial operation.
Critical note:
Avoid using in environments with phosphate ester-based lubricants or cutting fluid mist.
Buffer adjustment must be performed at 80% of maximum operating pressure.
