Specification notes
Q1: What is the FUJI LATEX FL M12–M16 Series?
A: The FL M12–M16 Series consists of adjustable long-stroke hydraulic shock absorbers designed for high-speed impact absorption in industrial machinery.
Q2: What models are included in the FL Series?
A: The series includes FL-1214H, FL-1417H, and FL-1620H with M12×1.0, M14×1.5, and M16×1.5 thread sizes respectively.
Q3: Is the FL Series fixed or adjustable?
A: The FL Series is adjustable. Damping can be changed using the adjustment knob at the bottom of the shock absorber and secured with the locking screw.
Q4: What does H mean in the FL model number?
A: H indicates the high-speed performance classification, with an impact speed range of 0.3–3 m/s.
Q5: What is the maximum absorption energy of the FL Series?
A: Maximum absorption energy reaches 17.6 J with FL-1620H. FL-1417H provides 14.7 J and FL-1214H provides 5.4 J.
Q6: What is the maximum equivalent mass?
A: Maximum equivalent mass reaches 60 kg with FL-1620H, compared with 50 kg for FL-1417H and 30 kg for FL-1214H.
Q7: What is the difference between FL-1214H, FL-1417H, and FL-1620H?
A: The main differences are thread size, stroke, absorption energy, and equivalent mass. The three models provide M12 / 14 mm, M14 / 17 mm, and M16 / 20 mm configurations respectively.
Q8: What end configurations are available?
A: The series offers -S capless and -C with cap configurations, with -R available when a urethane cap is required.
Q9: What should be considered when installing an FL shock absorber?
A: An external stopper and sufficient mounting strength are recommended. Eccentric loading should remain within ±2.5°, and installation in a vacuum or where oil may directly contact the product should be avoided.
Q10: How do I select the correct FL model?
A: Check moving mass, impact speed, absorption energy, required stroke, cycle rate, and thread size. The adjustable damping design can also be used to match changing operating conditions.
