Specification notes
Q1: What is the FUJI LATEX FA/FWM-B Series?
A: The FA/FWM-B Series consists of copper-free adjustable hydraulic shock absorbers for industrial machinery and production environments where copper ions are unacceptable.
Q2: What industries are suitable for the FA/FWM-B Series?
A: The series is suitable for lithium-ion battery production, automation equipment, precision manufacturing, and other processes with restrictions on copper-containing materials.
Q3: Does the FA/FWM-B Series use copper-containing materials?
A: No. The series is designed without copper-containing materials in its main components for applications where copper ions are unacceptable.
Q4: What orifice types are available?
A: The series includes single-orifice, multiple-orifice, and multiple-varying orifice types for different impact characteristics.
Q5: Which orifice type should be selected for different speeds?
A: Single-orifice models are mainly suited to low-speed impacts, multiple-orifice models to high-speed impacts, and multiple-varying orifice models to medium-speed impacts and pneumatic cylinder applications.
Q6: What is the maximum absorption energy of the FA/FWM-B Series?
A: Maximum absorption energy reaches 79.3 J, including the FA-B2725FB, FA-B2725FD, and FWM-B2725FBD models.
Q7: What is the maximum equivalent mass?
A: Maximum equivalent mass reaches 650 kg with the FA-B2725FB model.
Q8: What is the difference between FA/FWM-B and standard FA/FWM models?
A: The main difference is the copper-free material specification. External diameters are the same as the corresponding standard models, helping simplify replacement.
Q9: What should be checked during installation?
A: Ensure sufficient mounting strength, use an external stopper, avoid excessive eccentric loading, and confirm that impact speed, absorption energy, equivalent mass, and cycle rate are within the applicable range.
Q10: How do I select the correct FA/FWM-B model?
A: Check moving mass, impact speed, drive method, absorption energy, cycle rate, thread size, stroke, and orifice type, or contact GATO Corporation for model selection support.
