Specification notes
Q1: What is the FUJI LATEX FSB M12–M16 Series?
A: The FSB Series consists of fixed hydraulic shock absorbers integrated into a stopper-bolt form for compact industrial machine end stops.
Q2: What models are included in the FSB Series?
A: The series includes FSB-1205-C, FSB-1407-C, and FSB-1609-C with M12×1.75, M14×2, and M16×2 thread sizes.
Q3: Is the FSB Series fixed or adjustable?
A: The FSB Series is fixed and does not require damping adjustment.
Q4: What orifice structures are used in the FSB Series?
A: FSB-1205-C uses a single-orifice structure, while FSB-1407-C and FSB-1609-C use multiple-orifice structures.
Q5: What is the maximum absorption energy of the FSB Series?
A: Maximum absorption energy reaches 6 J with FSB-1609-C. FSB-1205-C provides 0.68 J and FSB-1407-C provides 2.5 J.
Q6: What is the maximum equivalent mass?
A: Maximum equivalent mass reaches 50 kg with FSB-1609-C. FSB-1205-C and FSB-1407-C are rated at 5 kg and 20 kg respectively.
Q7: What is the impact speed range?
A: All three FSB models operate within an impact speed range of 0.3–1 m/s.
Q8: Are FSB thread pitches the same as other shock absorbers?
A: Not necessarily. The FSB specifications note that the thread pitches differ from those of other absorber models, so the M12×1.75, M14×2, and M16×2 thread sizes should be checked carefully during replacement.
Q9: What should be checked when installing an FSB shock absorber?
A: Provide sufficient mounting strength and an external stopper, keep eccentric loading within ±2.5°, avoid excessive tightening, and consider dust accumulation when the piston rod is installed facing upward.
Q10: How do I select the correct FSB model?
A: Check moving mass, impact speed, absorption energy, cycle rate, thread size, and available mounting space, then select FSB-1205-C, FSB-1407-C, or FSB-1609-C according to the machine conditions.
