Q: When should you use a ball socket, eyelet, threaded stud, or clevis fitting?
A: Ball sockets suit changing angles and help compensate for minor misalignment. Threaded studs provide compact, rigid connections. Eyelets create stable pin-based pivots. Clevis forks or blades are useful when quick removal, heavy-duty mounting, or limited clearance is required.
Q: Why do end fittings affect service life?
A: An unsuitable fitting can introduce side loads, binding, or misalignment that increase stress on the piston rod and seals. Hole diameter, pin size, thread size, mounting thickness, and angular movement must all match the application.
Q: How can corrosion resistance and maintenance be addressed?
A: Use stainless steel fittings in marine, medical, wet, and frequently cleaned environments. For maintainable equipment, use pin-compatible or modular fittings and record the fitting type, thread, pin size, and mounting orientation.
Conclusion: An end fitting is part of the load, alignment, and maintenance system. Select it only after the movement and mounting geometry have been defined.
