Installation Steps
-
Preparation
- Verify that the fisheye joint model matches the cylinder rod specifications
- Inspect the joint for damage or contamination
- Prepare necessary tools: wrench, thread locker (optional)
- Clean the cylinder rod threads and mounting surfaces
-
Mounting the Joint
- Screw the fisheye joint onto the cylinder rod end
- For M10 and smaller sizes, thread locker is recommended for enhanced fixation
- Tighten evenly to the recommended torque value (refer to the table below)
- Ensure the joint can rotate freely after installation
-
Connecting the Load
- Attach the load to the spherical part of the fisheye joint
- Secure with appropriate pins or bolts
- Ensure flexible movement of the load after connection
-
Installation Check
- Verify that the joint is securely installed without looseness
- Confirm the joint can rotate and oscillate freely
- Test cylinder movement to ensure no abnormal resistance or noise

Operation Guidelines
-
Before Initial Use
- Operate the cylinder 2-3 times under no-load conditions
- Check for smooth joint movement
- Confirm no abnormal noise or resistance
-
Normal Operation
- Ensure working pressure does not exceed 1.32MPa
- Avoid exceeding the recommended rotation angle range
- Regularly inspect the joint condition
- Keep the joint clean and free from contamination
-
Load Considerations
- Ensure the load direction aligns with the joint's rotation plane
- Avoid applying excessive radial loads
- Impact loads should not exceed 1.5 times the rated load

Maintenance
-
Daily Inspection
- Check for joint looseness
- Confirm smooth rotation
- Inspect for abnormal wear or damage
-
Regular Maintenance
- Every 3 months:
- Clean the joint surface
- Check thread connection status
- Retighten or apply thread locker if necessary
- Every 6 months:
- Comprehensive inspection of joint wear
- Test rotational flexibility
- Replace severely worn joints
-
Lubrication
- Additional lubrication is generally not required
- In harsh environments, add a small amount of grease every 3 months
- Use lithium-based grease or special pneumatic component lubricant
-
Storage
- Store unused joints in a dry, clean environment
- Avoid direct sunlight and high-temperature environments
- Storage temperature range: -10°C~40°C

Safety Precautions
- Do not exceed the recommended torque value during installation to avoid thread damage
- Avoid installing or removing the joint while it is under load
- Do not use the joint for purposes other than rotational movement
- Avoid use in environments with corrosive gases or liquids unless the joint has special protective treatment
- Regularly inspect the joint condition and promptly replace worn or damaged components
- Ensure the use of matching specification joints; do not mix different models or brands
- Reduce the rated load when using in high-temperature environments
- Always cut off the air supply during installation and maintenance
