Festo's new DGE-RF electromechanical linear actuator is capable of moving
payloads almost silently, at speeds of up to 10m/s. The belt-driven unit
is available in lengths of up to 5m as standard, or in extended lengths
to special order. Three variants support payloads of 5, 30 or 60kg, with
a repeatable positioning accuracy of +/-0.1mm. The virtually silent
operation is attributed to a low-friction roller-guide bearing located
inside the housing, which protects it against adverse environmental
conditions. This, together with the provision of grease reserves, ensures
that the actuator can operate for up to 10,000km before any routine
maintenance is necessary.
Interactive configuration software is available as a free download from
the Festo web site to help users achieve the correct motor/actuator match
for their application. The software calculates the optimum size and drive
options for specific speed and loading characteristics. When the
combination is decided, Festo is able to supply a range of accessories to
suit a particular machine build, including couplings, flanges and
sensors, as a single part number in fully- or semi-assembled form, as
required.
