Adjustable Relief Series KBM20-50- *

Adjustable Relief Series KBM20-50- *

If an oil pressure generated due to a collision exceeds the set pressure, the relief function is activated and the resistance force is maintained below a certain level. The set pressure can be adjusted.

[Features]
・Kayaba's unique porous orifice (KBM, KBMA, KBMD, KBA series) and tapered groove orifice (KBMT series) achieve ideal energy absorption and smooth stop.
· Even high speed shock such as injection molding picking robot shock can be stopped surely and softly.
· It is possible to stop smoothly with the low-speed series.
・As this product employs the oil lock mechanism, no bottoming occurs and the KYB mini buffer can be used as a stopper without any change.
・No stopper is needed.
・Two or more units can be used in parallel because there is less variability in performance.
・Being a Kayaba's unique porous orifice series, it can be used without adjustment within the usable range.
・Thanks to the sound-damping cap, quiet stoppage is achieved even when a high-speed collision occurs.
・Mountable in 360 degree directions.
・Available in a wide range of energy absorption from 1.2 to 392 J (0.12 to 40 kgf・m).
・Available in an energy absorption of 118 to 392 J (12 to 40 kgf・m) and a mounting screw diameter of M25 and M36 series.
・Adjustable utilizing a relief valve.
