LORD RD-8040-1 (short stroke) and RD-8041-1 (long stroke) dampers are compact, magneto-rheological (MR) fluid dampers suitable for industrial suspension applications. Continuously variable damping is controlled by the increase in yield strength of the MR fluid in response to magnetic field strength.

RD-8040-1 and RD-8041-1 Dampers
Debion
LORD RD-8040-1 (short stroke) and RD-8041-1 (long
stroke) dampers are compact, magneto-rheological (MR)
fl uid dampers suitable for industrial suspension applica-
tions. Continuously variable damping is controlled by the
increase in yield strength of the MR fl uid in response to
magnetic fi eld strength.
Features and Benefi ts
Fast Response Time – responds in less than 15 millisec-
onds to changes in the magnetic fi eld.
Easy to Use – provides simple electronics and straight
forward controls.
Durable – provides excellent long term stability.
Storage
Dampers should be stored at -40 to +100°C (-40 to
+212°F).
The RD-8040-1 and RD-8041-1 dampers are monotube
shocks containing high-pressure nitrogen gas (300 psi).
Handle with care and do not heat or puncture body

Explore the possibilities of devices from LORD. The LORD Wonder Box? Device Controller is a companion product for our devices. It allows you to explore the many control possibilities our technology can offer. The Wonder Box provides a closed-loop current control to compensate for changing electrical loads up to the limits of the power supply. Further, the Wonder Box may be operated as an interface device for PLC or computer control of our devices.
If manual operation is desired, a potentiometer is provided to control the current supplied to an attached device.
The Wonder Box is integral to devices and systems for a wide variety of applications.
