Specification notes
Q1: What is the FUJI LATEX FED Series?
A: The FED Series consists of fixed hydraulic shock absorbers designed for emergency-stop protection during machine overtravel, runaway conditions, or abnormal motion.
Q2: What models are included in the FED Series?
A: The series includes FED-2010M-C and FED-3020M-C with M20×1.5 and M30×1.5 thread sizes respectively.
Q3: Is the FED Series fixed or adjustable?
A: The FED Series is fixed and uses a variable-groove orifice structure without a damping adjustment mechanism.
Q4: Can the FED Series be used for normal repetitive operation?
A: The FED Series is intended for emergency-stop applications rather than normal repetitive machine operation.
Q5: What is the difference between FED-2010M-C and FED-3020M-C?
A: FED-2010M-C has an M20×1.5 thread, 10 mm stroke, and 19.6 J capacity. FED-3020M-C has an M30×1.5 thread, 20 mm stroke, and 98 J capacity.
Q6: What is the impact speed range of the FED Series?
A: Both FED-2010M-C and FED-3020M-C are rated for impact speeds from 0.5 to 2 m/s.
Q7: How many emergency operations can an FED shock absorber handle?
A: When used as an emergency absorber, the FED Series is rated for approximately 100 operations. Product condition should still be checked after emergency activation.
Q8: Can the FED Series accept eccentric loading?
A: No. Eccentric load must not be applied to the piston rod, and rotating applications require appropriate installation geometry.
Q9: Is an external stopper required?
A: Yes. An external stopper and sufficient mounting strength are required. Mounting strength should be designed at approximately two to three times the specified maximum drag.
Q10: How do I select between FED-2010M-C and FED-3020M-C?
A: Check moving mass, emergency impact speed, required absorption energy, stopping distance, thread size, and available mounting space. For higher emergency impact energy, FED-3020M-C may be the more suitable option.
