Shock Absorber, Coolant Resistant Type, RBL Series RBL2725S

Compact-type shock absorber that has been shortened lengthwise.
[Features]
· Absorbs impact and noise.
· Can be used in an environment where water insoluble cutting oil scatters (mainly JIS Class 1 equivalent).
· Allowable deviation angle is 5°.
· Ideal for absorption of rotational energy.
· Can be used without an external stopper.
· The robust body can be positioned directly.
· Automatically adjusts to the most appropriate energy absorption performance.
