Specification notes
Q1: What is the FUJI LATEX FK M64–M80 Series?
A: The FK M64–M80 Series consists of large fixed hydraulic shock absorbers for high-energy impact absorption in logistics systems, transfer equipment, and large machinery. Selected models are dedicated to emergency-stop applications.
Q2: What models are included in the FK M64–M80 Series?
A: The group includes FK-6450, FK-64100, FK-64150, FK-64200, FK-80200, FK-80300, and FK-80400, covering M64×2.0 and M80×2.0 thread sizes.
Q3: Is the FK M64–M80 Series fixed or adjustable?
A: The FK models listed on this page are fixed hydraulic shock absorbers designed for specified impact conditions and do not use a standard damping adjustment mechanism.
Q4: What do L, M, and H mean on the M64 models?
A: L, M, and H identify low-, medium-, and high-speed characteristics. Depending on the M64 model, impact-speed ranges extend up to 3.6 m/s.
Q5: What is the maximum absorption energy of the FK M64–M80 Series?
A: Maximum absorption energy reaches 38,800 J with FK-80400-C-***, which has a 400 mm stroke.
Q6: Can FK-64200 be used for normal repetitive operation?
A: No. FK-64200 is a made-to-order emergency-stop model and is specifically stated as not being designed for normal operation.
Q7: What are FK-80200, FK-80300, and FK-80400 designed for?
A: These M80 models are recommended for runaway protection and emergency-stop applications. Their maximum cycle rate is 1 cycle/min.
Q8: What is the difference between FK-80200, FK-80300, and FK-80400?
A: FK-80200 has a 200 mm stroke and 1,900 J capacity, FK-80300 has a 300 mm stroke and 28,900 J capacity, and FK-80400 has a 400 mm stroke and 38,800 J capacity.
Q9: What should be checked when installing an FK M64–M80 shock absorber?
A: Ensure sufficient mounting strength and an external stopper. Emergency-stop models require centered impact without eccentric loading, and the installation should be designed for the specified maximum drag.
Q10: How do I select the correct FK M64–M80 model?
A: For standard M64 models, check moving mass, impact speed, stroke, and absorption energy. For emergency-stop applications, confirm maximum runaway speed, total moving mass, stopping distance, required energy, and installation conditions, or contact GATO Corporation for selection support.
