Installation Steps
Determine Installation Direction: Select the appropriate installation method based on load direction and motion requirements
-
Secure the Cylinder: Fix the cylinder to the mounting surface using bolts with torque according to the following table:
- Bore diameter 6-10mm: Recommended torque 2-3N·m
- Bore diameter 15-20mm: Recommended torque 4-5N·m
- Bore diameter 25-32mm: Recommended torque 6-8N·m
-
Connect Air Supply:
- Connect the air supply using appropriate air hoses and fittings
- Ensure no air leakage and stable pressure
- Blow out impurities from the air hoses before installation
-
Install Accessories (if needed):
- Position sensors: Install in the grooves on the cylinder side as required
- Buffer devices: Adjust buffer screws to appropriate positions

3. Operation Guide
Basic Operation
-
Pre-Start Inspection:
- Confirm air supply pressure is within 0.05-0.7MPa range
- Check all connections are secure
- Manually test piston movement for smooth operation
-
Test Run:
- First perform low-speed test run, observe if cylinder movement is stable
- Check for abnormal noise or leakage
- Confirm piston stroke meets requirements
-
Normal Operation:
- Gradually adjust to normal working speed
- Regularly check operating status and performance

Normal Operation:
- Gradually adjust to normal working speed
- Regularly check operating status and performance
Speed Control
- Adjust extension and retraction speeds of the cylinder through flow control valves
- Recommended operating speed range: 30-800mm/s (varies depending on bore diameter)
- Avoid overspeed operation to prevent affecting cylinder lifespan
Pressure Adjustment
- Working pressure should be adjusted based on load size
- Minimum working pressure: 0.05MPa (for bore diameters 25-32mm)
- Maximum working pressure: 0.7MPa
- Test pressure: 1.05MPa
Operating Environment
- Ambient temperature: -10°C to 60°C (no freezing)
- Working medium: Clean, dry compressed air (40μm filter recommended)
- Avoid use in corrosive environments; take protective measures if necessary
